IMPORTANT: you need to complete the PDP thinking process your program. Turn in item:
1) one complete PDP for the program.
2) directory_file.py – this program allows users to contribute to and view a text file containing usernames and emails
Use our menu-based program model – you can adapt the ch5_dictionary_starter.py in D2L resources – but
this time we use a file, not a dictionary, for the data source!
The user has three options - view, add and exit – delete un-needed code, and adapt a function for each menu choice
At the start of the program, create your .txt file in 'w' mode, with one sample entry (see 1* view output below)
User can choose to add to the text file by inputting a username and email. The input string can include multiple
contacts, by using a comma to separate each contact's info from the next.
User can also simply choose to read names
rier - Vier saenana//anail fila
add - Add aenana (a)/email (a) to the fila
Reit - Exit peogran
and email addresses from the .txt file.
Notes: initially create the file in 'w' write mode, Connand: vier
