isspace() method in Python is used to check if all characters in a string are whitespace characters. This includes spaces (' '), tabs (\t), newlines (\n), and other Unicode-defined whitespace characters. This method is particularly helpful when validating input or processing text to ensure that it contains only whitespace characters.

Let’s understand this with the help of an example:

Python 
s = "   " print(s.isspace())

Output
True

Explanation:

  • The string " " contains only whitespace characters (spaces).
  • The isspace() method returns True since all characters in the string are whitespace.

String with mixed characters

Let’s see what happens when the string contains non-whitespace characters:

Python 
s = "Python is fun! "  print(s.isspace())

Output
False

Explanation:

  • The string contains non-whitespace characters ("Python is fun!").
  • The presence of these characters causes the method to return False.

String with tabs and newlines

isspace() method considers tabs and newlines as whitespace characters:

Python 
s = "\t\n"  print(s.isspace())

Output
True

Explanation:

  • The string contains only a tab (\t) and a newline (\n), both of which are valid whitespace characters.
  • The method returns True.
