How do I print two strings vertically side by side [duplicate]

Answer 1

To get your current code to work, you should use the or operator in your condition instead of and, and use a conditional operator to default your list values to a space if the index is not less than the length of the list:

s1 = 'hello'
s2 = 'paul'
i = 0
while i < len(s1) or i < len(s2):
    print(s1[i] if i < len(s1) else ' ', s2[i] if i < len(s2) else ' ')
    i += 1
