Delete a row from a text file with Python

Question

I have a file where each line starts with a number. The user can delete a row by typing in the number of the row the user would like to delete.

The issue I\'m having

Answer 1

You don't need to check for the lines numbers in your file, you can do something like this:

def DeleteToDo(self):
    print "Which Item Do You Want To Delete?"
    DeleteItem = int(raw_input(">")) - 1
    print "Are You Sure You Want To Delete Number" + str(DeleteItem) + "(y/n)"
    VerifyDelete = str.lower(raw_input(">"))
    if VerifyDelete == "y":
        with open(ToDo.filename,"r") as f:
            lines = ''.join([a for i,a in enumerate(f) if i != DeleteItem])

        with open(ToDo.filename, "w") as f:
            f.write(lines)
    else:
        print "Nothing Deleted"
