Python | Remove unwanted spaces from string
Sometimes, while working with strings, we may have situations in which we might have more than 1 spaces between intermediate words in strings that are mostly unwanted. This type of situations can occur in web development and often needs rectification. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using re.sub()
This problem can be performed using the regex in which we can restrict the separation between the words to be just a single space using the appropriate regex string.

# Python3 code to demonstrate working of# remove additional space from string# Using re.sub()import re # initializing string test_str = "GfG is good website" # printing original string print("The original string is : " + test_str) # using re.sub()# remove additional space from string res = re.sub(' +', ' ', test_str) # printing result print("The strings after extra space removal : " + str(res)) |
The original string is : GfG is good website The strings after extra space removal : GfG is good website
Method #2 : Using split() and join()
This task can also be performed using the split and join function. This is performed in two steps. In first step, we convert the string into list of words and then join with a single space using the join function.
# Python3 code to demonstrate working of# remove additional space from string# Using split() + join() # initializing string test_str = "GfG is good website" # printing original string print("The original string is : " + test_str) # using split() + join()# remove additional space from string res = " ".join(test_str.split()) # printing result print("The strings after extra space removal : " + str(res)) |
The original string is : GfG is good website The strings after extra space removal : GfG is good website
