Python | Check for spaces in string

Sometimes, we might have a problem in which we need to check if the string has any of blank spaces. This kind of problem can be in Machine Learning domain to get specific type of data set. Let’s discuss certain ways in which this kind of problem can be solved.

Method #1 : Using regex
This kind of problem can be solved using the regex utility offered by python. By feeding the appropriate regex string in search(), we can check presence of space in a string.

# Python3 code to demonstrate working of
# Check for spaces in string
# Using regex
import re
  
# initializing string 
test_str = "Geeks  forGeeks"
  
# printing original string 
print("The original string is : " + test_str)
  
# Using regex
# Check for spaces 
res = bool(re.search(r"\s", test_str))
  
# printing result 
print("Does string contain spaces ? " + str(res))

Output :

The original string is : Geeks  forGeeks
Does string contain spaces ? True

Method #2 : Using in operator
This task can also be performed using in operator. Just required to check for a space in the string. The verdict returned is true even if a single space is found and false otherwise.
