'''
I am creating a bank statement that keeps track of transactions
  and only user with correct name and password can access the statement.
The program will ask the user to input his/her name and password.
It will requires the user to input the information correctly otherwise, he/she can't view the bank statements.
The programs will allow the user to input his/her name and password 4x before it ends the program.
The banking records will appears and saved in a text file.

The program includes the following criteria:

    function that takes at least two user arguments from the command line (not the input function)
    Contain at least one if/else statement
    Perform a calculation on a list
    Use at least one dictionary
    Have one try/except statement
    Write either output or a graph to a file
    Must include docstrings telling us how to run your script
    Each function must be documented with comments telling us what the purpose of the function is, and what it's inputs and outputs are
    Either create a class to contain the related functions OR output a simple graph
    Upload your final python script or jupyter notebook to Github, turn in the link on Canvas
