Write a function 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 the function clear_screen.

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()
Does the assignment implement new_line, three_lines, nine_lines, and clear_screen functions, as well as a main section of the program which calls the functions? Does the assignment demonstrate the use of nested function calls?
