Python : Expenditure App
Expenditure Application
The Menu:
Continuing parts of the Expenditure Application, here is the basic menu that we will use in our app. We will select (9) as Exit from the system.
So now, we have a json file with sample data and stored in a directory, also we have a file called “expen.py” and we will write the menu def in it and save it.
def the_menu(): # This is a menu
print(‘1. Add New Entry.’)
print(‘2. Delete an Entry.’)
print(‘3. Change an Entry.’)
print(‘4. Show Total Expenditure in a Year.’)
print(‘5. Show Expenditure Details in a year.’)
print(‘9. Exit.’)
# This line will ask the user to enter the operation he want to do.
choice = input(‘What you want to do? ‘)
return choice
In this app we will have 5 functions as our menu and maybe one or two functions to facilitate some calculations in background.

leveling the Ground:
In this post we will assume that we have a folder for our application, and we will create two files one is for our python code and we will name it “expen.py”, the other is for our data and we will name it “expen_dat.json” this file extension is ‘json’. Also I assume that we have json pack is installed in the PC so if you don’t have json this is the time to install it.
json file:After you create expen_dat.json file just open it with any text editor and copy a test data of our expenditure as shown.
{“expenditure”:
[
{“date”:”02/03/2016″,”amount”:300},
{“date”:”10/04/2016″,”amount”:550},
{“date”:”02/05/2016″,”amount”:300},
{“date”:”10/04/2016″,”amount”:550},
{“date”:”02/03/2016″,”amount”:300},
{“date”:”10/04/2016″,”amount”:550},
{“date”:”05/01/2017″,”amount”:400},
{“date”:”10/02/2017″,”amount”:400},
{“date”:”15/03/2017″,”amount”:400},
{“date”:”20/04/2017″,”amount”:400}
}]
In next post we will start with coding and testing our Expenditure Application.
I will use the @pycharm to write the code and test it, but any other code editors can be used. Also, I assume we have Python and json installed in your PC.

Expenditure Application
In this post, we will go through the case study of our application.
‘ The Case’
We want to build an application to store and retrieve some data regard our expenditure, we will go as simple as two keys (date and amount), and we will save the data in a json file. So to view the data we need some functions to do some operations on the data such as Add, Delete, retrieve and change.
I will use the @pycharm to write the code and test it, but any other code editors can be used. Also, I assume we have Python and json installed in your PC.
Follow me on Twitter..Python Project: Expenditure App Part 1
Python Project:
Two months back I start to learn #Python “Python is a #computer #programming #language “, you can say it grabbed me very quickly. I start to read some #sample #code from the net, then downloading the requirement and after 10 working days I was writing #codes in python and doing what I love ‘Solving #mathematics puzzles with #python’.
So I decide to contribute in training or publishing python language by posting some codes block with explaining and comments, also by developing an application so we will learn on a real example.
I am publishing some codes on my Twitter (@h_ta3kees):
https://twitter.com/h_ta3kees?s=09
and I will do the same here on my blog.
The coming posts will be about the application that we will start develop I will call it ‘Expenditure App’.
