Python: Coffee Consumption – P6

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-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')
     # 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. > ')    
        elif (cn_id ==" ") or (cn_id =="") or (check_availabilty('coffee_name','cn_id', int(cn_id)) != None):

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. > ')    
        elif sex in ['m','M','f','F']:
            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):
            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.

..:: Have Fun with Coding ::.. 🙂
