Answer to Question #237306 in Python for Joel

Question

Write a function in this file called nine_lines that uses the function three_lines (provided below) to print a total of nine lines.

Now add a function named clear_screen that uses a combination of the functions nine_lines, three_lines, and new_line (provided below) to print a total of twenty-five lines. The last line of your program should call first nine_lines and then the clear_screen function.

The function three_lines and new_line are defined below so that you can see nested function calls. Also, to make counting “blank” lines visually easier, the print command inside new_line will print a dot at the beginning of the line:

def new_line():

print('.')

def three_lines():

new_line()

new_line()

new_line()

Answer 1

def new_line():

  print('')




def three_lines():

  new_line()

  new_line()

  new_line()




def nine_lines():

  three_lines()

  three_lines()

   

def clear_screen():

  nine_lines()

  three_lines()

  new_line()




   

   




print('.')

new_line()

print('.')

three_lines()

print('.')

nine_lines()

print('.')

clear_screen()
