Python String isspace() method returns “True” if all characters in the string are whitespace characters, Otherwise, It returns “False”. This function is used to check if the argument contains all whitespace characters, such as:
- ‘ ‘ – Space
- ‘\t’ – Horizontal tab
- ‘\n’ – Newline
- ‘\v’ – Vertical tab
- ‘\f’ – Feed
- ‘\r’ – Carriage return
Python String isspace() Method Syntax
Syntax: string.isspace()
Returns:
- True – If all characters in the string are whitespace characters.
- False – If the string contains 1 or more non-whitespace characters.
Python String isspace() Method Example
Python3
string = "\n\t\n"print(string.isspace()) |
Output:
True
Example 1: Basic Intuition of isspace() in Program
Here we will check whitespace in the string using isspace() program.
Python3
# checking for whitespace charactersstring = 'GeeksforLazyroar'print(string.isspace()) # checking if \n is a whitespace characterstring = '\n \n \n'print(string.isspace())string = 'Geeks\nfor\nLazyroar'print( string.isspace()) |
Output:
False True False
Example 2: Practical Application
Given a string in Python, count the number of whitespace characters in the string.
Input : string = 'My name is Ayush' Output : 3 Input : string = 'My name is \n\n\n\n\nAyush' Output : 8
Algorithm:
- Traverse the given string character by character up to its length, check if the character is a whitespace character.
- If it is a whitespace character, increment the counter by 1, else traverse to the next character.
- Print the value of the counter.
Python3
# Initialising the counter to 0string = 'My name is Ayush'count=0 # Iterating the string and checking for whitespace characters# Incrementing the counter if a whitespace character is found# Finally printing the countfor a in string: if (a.isspace()) == True: count+=1print(count)string = 'My name is \n\n\n\n\nAyush'count = 0for a in string: if (a.isspace()) == True: count+=1print(count) |
Output:
3 8
