Question

Can someone help me out with this one? I'm not sure why my code is not working

Answer 1

Answer:

Add this statement at the end of your steps() function

return ""

This statement will not print None at the end of steps.

Explanation:

Here is the complete function with return statement added at the end:

def steps(number):  # function steps that takes number (number of steps to print) as parameter and prints the steps specified by number

   i = 1  #assigns 1 to i

   while i < number + 1:  

       string = str(i) * 3  #multiplies value of i by 3 after converting i to string

       string1 = str(string)  # stores the step pattern to string1

       if i != 0:  # if the value of i is not equal to 0

           string1 = (i * 4*' ' + "\b" + "\b" + "\b" + "\b") + string  #set the spaces between steps

       elif i == 1:  # if value of i is equal to 1

           string1 = string  #set the string to string1

       print(string1)  # print string1

       i = i + 1  # increments i at each iteration

   return "" #this will not print None at the end of the steps and just add a an empty line instead of None.
