Assignment:
Writing a Python
program to determine whether a password exactly meets the following
requirements for a secure password:
- the length
of the password must be greater than some minimum length and less than
some maximum. You should decide on the minimum (at least 6) and maximum
(at least 15) allowable lengths; - it
must not include any spaces; - it must
contain at least one digit; and - it must
contain at least one alphabetic character.
Your program must contain at least
three functions:
- one function
to check that the password is the proper length; - a second
function to check whether it contains the required number of
characters/digits (Hint: to determine whether it contains at least one
digit and one alphabetic character, use a loop and the isalpha or isdigit methods);
and - a third
function to verify that it does not contain the prohibited character
(space).
Your program should prompt the user
for the candidate password and then each function and display either that the
password is valid or the first reason it is invalid.
You cannot use Regular Expressions
(RE) !
Your program should include Header
comments (what the program does) and in-line comments (the major design
steps). Document the values you chose for the min and max length
values.
Submit your Python program as a text
file (.py) file. In addition, submit a Design outline and a Test plan/report
(at least 3 different test cases – testing all the requirements) in a Word
document or a PDF file and include a screenshot of execution of your program
for each test case.
Your submission must also adhere to
the Submission Requirements document. (i.e., Filename and display your name,
class, date in the output).
