如何在 Python 中去除空格

s = '   canada  '
print(s.rstrip())  # For whitespace on the right side use rstrip.
print(s.lstrip())  # For whitespace on the left side lstrip.
print(s.strip())  # For whitespace from both side.
s = ' \t  canada  '
print(s.strip('\t'))  # This will strip any space, \t, \n, or \r characters from the left-hand side, right-hand side, or both sides of the string.

Output:

   canada
canada  
canada
          canada
