Python: Coffee Consumption – P7

September 8, 2021 Leave a comment

Learning : Python, SQlite3, Dataset, Pandas,
Subject: Create Coffee Consumption Application.

[NOTE: To keep the code as simple as we can, We WILL NOT ADD any user input Varevecations. Assuming that our user will Enter the right inputs.]

[ IF THE IS FIRST TIME DOWNLOADING THE CODE FILE, SELECT OPTION 7 FROM MAIN-MENU TO CREATE THE DATABASE]


In this part (Part-7) of Coffee Consumption App, we will write a Function to display all Records in the data-base in a table on the screen.

Beginning with formating the table header, we will have the following columns: record Id, Date_time, Coffee_name, Coffee_type, coffee_size, customer_Gender and Rank. Here is the code..

print(‘ ‘*6,’ID’,’ ‘*5,’ Date & Time’,’ ‘*3,’ Coffee Name’,’ ‘*4,’Type’,’ ‘*9,’Size’,’ ‘*4,’ Gender’,’ ‘*4,’ Rank’)
print(‘ ‘*4,’-‘*90)

Next we will execute an SQLITE command to fetch all the records. Here is the commands..
c.execute (f”select * from coffee_con where c_id > 1 “)
dataset = c.fetchall()

Also we will using the lookup tables to get the names using the id keys in the coffee_name, coffee_type, coffee_size columns.

Now, Using the for loop to access all the records and print them on the screen. Here is apart of the code ..


print(‘ ‘*6,'{}’.format(data_id),end=””)
print(‘ ‘*(10 – 5),'{}’.format(data_date),end=””)
print(‘ ‘*(21 – 16),'{}’.format(data_name[0]),end=””)
print(‘ ‘*(14 – len(data_name[0])),'{}’.format(data_type[0]),end=””)
print(‘ ‘*(13 – len(data_type[0])),'{}’.format(data_size[0]),end=””)
print(‘ ‘*(13 – len(data_size[0])),'{}’.format(data_sex),end=””)
print(‘ ‘*(12 – 1),'{}’.format(data_rank))

Here is a screen shot of the code..

Python: Coffee Consumption – P6

September 5, 2021 1 comment

Learning : Python, SQlite3, Dataset, Pandas,
Subject: Create Coffee Consumption Application.

[NOTE: To keep the code as simple as we can, We WILL NOT ADD any user input Varevecations. Assuming that our user will Enter the right inputs.]

[ IF THE IS FIRST TIME DOWNLOADING THE CODE FILE, SELECT OPTION 7 FROM MAIN-MENU TO CREATE THE DATABASE]


In this part (Part-6) of Coffee Consumption App, we will write First Function of the Main Application to ADD New Record. In this Function we will do the following:

  • Get the Current Date and Time.
  • The user will Select the Coffee Name, Type and Size from the list in lookup tables.
  • Selecting the Gender of the user.
  • Entring the Rank for the order [If the customer rank it].

Beginning with adding New Record in the Coffee Consumption System. We will use the datatime.now() function get the current data and time here is the code..

now = datetime.now()
date_t = now.strftime(“%d/%m/%Y %H:%M”)
Then we will show each of the lookup table we have and the user will select the ID of the Coffee Name,Type and Size, the, we will use a simple Validation process to control the user inut. Here is the code for Entering the Coffee Name


   # Select a Coffee Name 
    print('\n     List of Coffee Names:\n')
    show_list('coffee_name','cn_id')
     # check the availability of the input 
    while True:
        cn_id = input('\n     Enter the ID of a Coffee Name. [E to Exit]. > ')
        if cn_id in ['e','E']:
            input('     You Select [E to Exit].. Press any Key. > ')    
            return
            
        elif (cn_id ==" ") or (cn_id =="") or (check_availabilty('coffee_name','cn_id', int(cn_id)) != None):
            break

The same code will be apply for the Coffee Type and Coffee Size.
[NOTE] All the codes will be in the file to be Download.

Next part of the code will be to select the customer Gender [M,F] here also we will use a simple Validation that will accept M or F Not anything else. Here is the code..


# Select Customer Gender [Only M,F]
    while True:
        sex = input('\n     Enter the Gender of the customer. [M / F] [E to Exit]. > ')
        
        if sex in ['e','E']:
            input('     You Select [E to Exit].. Press any Key. > ')    
            return
        elif sex in ['m','M','f','F']:
            break
        else: 
            print('     You Must input [M,F]')

Last variable we will collect will be the Rank, the Customer will ask the user to Rank this Order, the range will be from 1 to 10, 0 will be for Not Available.. Here is the code…


# Enter the user Rank
    print('     If the User can Rank the Coffee.. 1 to 10 [1 is Bad, 10 is Great]')
    while True :
        rank = input('\n     Enter User Rank.[1 is Bad, 10 is Great] [0 is NOT Available] [E to Exit]. > ')
        if int(rank) in range (0,11):
            break
        else:
            print('\n     Rank Should be in Range of 0-10.'

After that we will display all the Entries on the screen and ask the customer to press [S] to save the Record, and then we will use IINSERT SQL command to Insert the record. Here is the code for all the function….



What’s Coming: In Part-7 we will do the Follwing:

Writing three Function to Show / Display the Records in the main Table of the Coffee Consumption Application.

[ IF THE IS FIRST TIME DOWNLOADING THE CODE FILE, SELECT OPTION 7 FROM MAIN-MENU TO CREATE THE DATABASE]


In this part (Part-5) of Coffee Consumption App, we will write all three Function to manage the Coffee Size (Mug Size).

  • Create Function: Add New Coffee Size.
  • Create Function: Edit a Coffee Size.
  • Create Function: Delete a Coffee Size.

Beginning with adding new Coffee Size, we will ask the user to enter a New Coffee Size, then we simply added to the databasde using SQL Insert command. … Here is the Code ..

Python: Coffee Consumption – P3

August 22, 2021 4 comments

Learning : Python, SQlite3, Dataset, Pandas,
Subject: Create Coffee Consumption Application.

[NOTE: To keep the code as simple as we can, We WILL NOT ADD any user input Varevecations. Assuming that our user will Enter the right inputs.]


[ IF THE IS FIRST TIME DOWNLOADING THE CODE FILE, SELECT OPTION 7 FROM MAIN-MENU TO CREATE THE DATABASE. ]


In this part (Part-3) of Coffee Consumption App, we will fill in some code into selected Functions. We will do the following:

  • Create Function: Show list.
  • Create Function: is_available.
  • Create Function: Manager Menu.
  • Create Manager Coffee Name Functions: Add, Edit, Delete

So, let’s start with writing the Manager Menu Function and a while loop to take the user selection and trigger the corresponding Function… Here is the Code ..

python project sql code coffee consumption ali radwani

We have two functions to help us in this application, one of them called def show_list(dt,d_id) is to Display the Data we have in the Lookup Tables based on the user selection function. The Function will take two arguments:
dt: data-table (Coffee Name, Coffee Type, Coffee Size)
d_id: id column name, and returning nothing.

Fisrt, let’s look at this Function:

python project sql code coffee consumption ali radwani


The second Function will be used to check if the user selection is available in the database, we will call it def is_available (dt, d_id, check_id) this Function is to check if the passed ID available in the data-set or not. The Function will take three Arguments as:
dt: Data-Table, d_id : Name of id column, check_id : The id we want to search for, and it will Return the data-set. After return, if dataset is empty that’s mean selected id is not available.

Now let’s see the function code..



Now we will start writing first three functions to manage the Coffee Name, and will start with Adding New Coffee Name to the lookup Table.
In coming code first we will call the header then show_list(‘coffee_name’,’cn_id’) passing Table Name:’coffee_name’ and id column:’cn_id’ to display the Coffee Names we have on the sccreen. Then we will ask the user to enter the New Name to be added to the database. Here is the Full code..

python project sql sqlite code coffee consumption ali radwani



Next we will write the Edit Function, and again after the header and show_list(‘coffee_name’,’cn_id’) we will ask the user to enter the ID of the Coffee Name to be change, here we will do a simple validation on user input. After that we will update the record that the user select. Here is the code..

python project sql code coffee consumption ali radwani



Last Function in this part is to Delete a selected Coffee Name by selection it’s ID, as in the Edit Fnction, the user will select an Id, we will check the availability the will execute the Delete command. Here is the code..


What’s Coming: In Part-4 we will do the Follwing:

Writing three Function to Manage the Coffee Type, Functions are: Add New Coffee Type, Edit Coffee Type and Delete a Coffee Type.

Python: Coffee Consumption – P2

August 17, 2021 5 comments

Learning : Python, SQlite3, Dataset, Pandas,
Subject: Create Coffee Consumption Application.

[NOTE: To keep the code as simple as we can, We WILL NOT ADD any user input Varevecations. Assuming that our user will Enter the right inputs.]


In this part (Part-2) of Coffee Consumption App, we will fill in some code into selected Functions. We will do the following:

  • Calling the Main-Menu Function.
  • Create header function.
  • Create the DataBase.
  • Create the Tables.
    • Insert the Zero records.
    • Insert data into Lookups Table.

So, let’s start with writing the main application body and calling the Main-Menu to trigger a Function based on the user selection. This section will be a calling the main_menu() in a while loop .. here is the code ..

# Main application body

while True :
    user_select = main_menu()

    if user_select == '1' :
        new_data() 

    if user_select == '2' :
        edit_record()

    if user_select == '3' :
        delete_record() 

    if user_select == '4' :
        #delete_record()
        pass 
        
    if user_select == '6' :
        c_name_type_size_manager() 
         
    if user_select == '7' :
        create_data_base()
    
    if user_select == '99' :
        input('\n\n   Thank you for using this Appliation. Press Enter.. > ')
        break



If we run the application now, we will see the main-menu but nothing will work because we still did not write any real Functions in the application.

Tables and Zero records:
Now we will write tha function to create the Tables and inserting the Zero record in each of them. All the codes will be in a function called: def create_data_base () : here are the name of the tables we will create:
coffee_con
coffee_name
coffee_type
coffee_size

and here is the full code in the function, in first part we will create the tables, second part will insert the zero record, last we will insert data in the lookup tables (coffee_name, coffee_type and coffee_size)

# def create_data_base () 

def create_data_base () :
    os.system('clear')
    
    line2 ="Create Data Base"
    header(line2,3,11)
    
    print('\n     All the data in the Data-Base will be removed, and can''t be retrieved. ')
    
    if input('\n     Press [Y] to Continue, anything else will Stop and Exite.  > ') not in ['y','Y'] :
        input('\n     You Select to stop and Exit. Press any Key .. >  ')
        return 
    
    # Part 1: CREATE TABLE:
    sql_coffee_con_t = "CREATE TABLE if not exists coffee_con (c_id INTEGER PRIMARY KEY AUTOINCREMENT, date_t,cn_id int, ct_id int, cs_id int, sex text, rank int )" 
    sql_coffee_name_t = "CREATE TABLE if not exists coffee_name (cn_id INTEGER PRIMARY KEY AUTOINCREMENT, c_name text )" 
    sql_coffee_type_t = "CREATE TABLE if not exists coffee_type (ct_id INTEGER PRIMARY KEY AUTOINCREMENT, c_type text )" 
    sql_coffee_size_t = "CREATE TABLE if not exists coffee_size (cs_id INTEGER PRIMARY KEY AUTOINCREMENT, c_size text )" 
    
    
    # Execute the commands
    c.execute(sql_coffee_con_t) 
    db_conn.commit() 
    c.execute(sql_coffee_name_t)
    db_conn.commit()
    c.execute(sql_coffee_type_t)
    db_conn.commit()
    c.execute(sql_coffee_size_t)
    db_conn.commit()
    
    
    # Part 2: Inserting ZERO records. 
    c.execute ("INSERT INTO coffee_con (date_t , cn_id, ct_id, cs_id, sex, rank) VALUES(:date_t , :cn_id, :ct_id, :cs_id, :sex, :rank)",{'date_t':'0' ,'cn_id' :0,'ct_id' :0,'cs_id' :0,'sex' :'0','rank' :0}) 
    db_conn.commit()
    c.execute ("INSERT INTO coffee_name (c_name) VALUES(:c_name )",{"c_name":'0'})         
    db_conn.commit() 
    c.execute ("INSERT INTO coffee_type (c_type) VALUES(:c_type )",{"c_type":'0'}) 
    db_conn.commit() 
    c.execute ("INSERT INTO coffee_size (c_size) VALUES(:c_size )",{"c_size":'0'}) 
    db_conn.commit() 
    
    
    
    # Part 3: Inserting Basic Information 
    coffee_Name_list = ['Black','Latte','Espresso','Americano','Cappuccino','Mocha', 
                     'Lungo', 'Flat white', 'Irish', 'Macchiato','Ristretto','Iced coffee']
        
    coffeeType_list = ['3n1' ,'Pods','Grounded']
    
    coffeeSize_list = ['Samll', 'Medium', 'Large', 'Venti']
    
    for each in coffeeName_list:
        c.execute ("INSERT INTO coffee_name (c_name) VALUES(:c_name )",{"c_name":each}) 
        db_conn.commit() 

    for each in coffeeType_list:
        c.execute ("INSERT INTO coffee_type (c_type) VALUES(:c_type )",{"c_type":each}) 
        db_conn.commit() 
    
    for each in coffeeSize_list:
        c.execute ("INSERT INTO coffee_size (c_size) VALUES(:c_size )",{"c_size":each}) 
        db_conn.commit() 

    input('\n\n     Data-Base Created, Basic Information Inserted. press any key to continue. > ')

[ The Full Code is Available in Download Page. ]

Last Function in this part is the header, it’s just a Title that will bee displayed in a box at the top of each page. Here is the code ..

# Header of the Application

def header(line2,b_l2,a_l2):
    os.system('clear')
    # The Project Name.
    line_1 = "Coffee Consumption"
    stars = 40 
    print('\n',' '*4,'*'*stars)
    print(' '*5,'***',' '*5,line_1,' '*7,'***')  
    print(' '*5,'***',' '*(stars - 8),'***')
    print(' '*5,'***',' '*b_l2,line2,' '*a_l2,'***')
    print(' '*5,'***',' '*(stars - 8),'***')
    print(' '*5,'*'* stars,'\n')


What’s Coming: In Part-3 we will do the Follwing:

  • Writing a function show_list.
  • Writing the function to Add New Coffee Name.
  • Writing the function to Edit a Coffee Name.
  • Writing the function to Delete a Coffee Name.
