Given this code:
for num in range(4):
the loop will repeat this number of iterations.
What is 4 times?
This type of function carries out a task and returns one or more values.
What is a value-returning function?
If we have a numeric value we wish to write into a text file, this value should first be converted into a text or string type using this function.
