Introduction

I want to display following print in Command line.
apple
  apple
    apple
      apple
        apple

Miss

However, This print is not able to display following code used print script.

def main():
    i = 0
    while i<5:
        print('apple')
        j = 0
        while j < i:
            print(' ')
            j = j + 1
        i = i + 1
if __name__ == '__main__':
    main()

rusult…

Print code change line when writing new apple.

Please, look at following code.

import sys

def main():
    i = 0
    while i < 5:
        print('apple')
        j = 0
        while j <= i:
            sys.stdout.write(' ')
            j = j + 1
        i  = i + 1
if __name__ == '__main__':
    main()

sys.stdout.write is write string regardless of the changing line.
Result!

However, I give you a strong warning that sys.stdout.weite use only str.
