Can u make sure to separate the function and the main file. Also, can u please make sure to use loops (in the function). As well, can u use the .format (from python 3). Lastly, can u make sure to only use one return statement in the function (at the end of the function). Thank you for your time.

Q3: In mathematics, the notation nl represents the factorial of a nonnegative integer n. The factorial of n is the product of all the nonnegative integers from 1 to n. Forexample, ?!=1>=5,l]40 and 4!:1x2x3x4=24 Write a function called factorial that takes a nonnegative integer num as a parameter then uses a for loop to calculate and return the factorial of that number. If the user enters a negative number, the function returns the integer 1. Save the function in a PyDev library module named 36_funct ions . py {same as other questions) Write a main program named q3.py that tests the function by asking the user to enter a number and displaying the output. \"Sample run for qS.pi,Ir Enter a positive integer: 7 TI". = 5040 CP 104 Fall 2019 \"Sample run for q3.py Enter a positive integer: -7 You did not enter a positive integer - Test your program with 2 different values for numthat are different than the example. One of those must cause the program to display the error message. 0 The input and output both are performed in the q3.py - Copy the results to testing. txt. I Assume: user will enter only integer values, positive or negative
