Simple Expense Tracker Program Using Python - Free Assignment Solution

In this assignment you are only able to use the standard python library. No third parties library allowed. Our expert will make you learn how to utilize various data structures, implement iteration and conditionals, handle exceptions, and write unit tests, ensuring your code is comprehensive and accessible for users with varying levels of Python knowledge. The program should be able to sort by category, month, and year, dollar amount. The program should also be able to sum the transactions amount by category, month/year. 
  
1.    The application must include at least the minimum number of each of the following: 

• 4 container types (list, tuple, set AND dictionary) that are used by the application 
• 1 iteration type (for, while) 
• 1 conditional (if) 
• 1 try block with an else condition 
• 1 user-defined function that accepts parameters/arguments and/or returns a value. 
• 1 input and/or output file (include input data with your project) 
• 1 user-defined class. The class must be imported by your main program from a separate file and have the following required structures. 
  • at least 1 private and 2 public self class attributes 
  • at least 1 private and 2 public class methods that take arguments, return values and are used by your program 
  • an init() class method that takes at least 1 argument  a repr() or str() class method 
  • a magic class method (not one of the methods listed above) 

2.    Provide 2 unit tests that prove two of your public class methods work as expected. The tests should evaluate results using assert statements.
