python: easiest way to get a string of spaces of length N

Question

What's the easiest way to generate a string of spaces of length N in Python?

(besides something like this, which is multiline and presumably inefficient for large n:

def spaces(n):
  s = ''
  for i in range(n):
    s += ' '
  return s

)

Answer 1

You could do it as a function:

def spaces(n):
    return ' ' * n

Or just use the expression:

' ' * n

Answer 2

try this, simple, only one line:

    ' ' * n
