Create a project folder username_a06. Place all your tasks python files(t01.py ,
t02.py ,t03.py) and the testing file testing.txt inside this folder. Upon
completing your tasks, export your projrct folder to username_a06.zip file, validate it, and
submit it to the dropbox by the due date.
Write and test the following function:
def winner():
Add the function to a Python module named functions.py.
Test it from .
winner takes no parameters and asks the user to enter a
series of strings that represent the output of a game with a loop. The
user should enter an empty string (just press or ) to signal the end of the series. After all strings have
been entered, the function returns two numbers representing how many
times the string "blue" appeared in the input and how many times the
string "grey" appeared in the input.
The function must use a while loop.
Provide the function docstring (documentation) following the CP103 style.
Sample execution:
winner()
Enter the winning team: blue Enter the winning team: blue Enter the winning team: grey Enter the winning team: blue Enter the winning team: grey Enter the winning team:
and returns:
3, 2
Test the function with three different sets of parameters.
Partial testing:
Write and test the following function:
def is_prime(num):
"""
-------------------------------------------------------
Determines if num is a prime number.
Use: prime = is_prime(num)
-------------------------------------------------------
Parameters:
num - a positive integer (int > 1)
Returns:
prime - True if num is prime, False otherwise (bool)
------------------------------------------------------
"""
Add the function to a Python module named functions.py.
Test it from .
A prime number is a positive integer greater than 1 which has no other factors except 1 and the number itself. 2, 3, 5, and 7 are prime numbers as they can only be divided by 1 and by themselves to give a whole number. 4 is not a prime because, 4 can be divided by 1, 2 and 4.
The function does not ask for input and does no printing - that is done by your test program.
The function must use a while loop.
Sample execution:
is_prime(9)
False
is_prime(131)
True
Test the function with three different sets of parameters.
Partial testing:
Write and test the following function:
def interest_table(principal, rate, payment):
"""
-------------------------------------------------------
Prints a table of monthly interest and payments on a loan.
Use: interest_table(principal, rate, payment)
-------------------------------------------------------
Parameters:
principal - original value of a loan (float > 0)
rate - yearly interest rate as a % (float >= 0)
payment - the monthly payment (float > 0)
Returns:
None

"""
Add the function to a Python module named functions.py.
