How to remove all spaces from a string?

Use the replace() method.

# Remove all spaces in a string
my_string = "This is a string with spaces"
string_without_spaces = my_string.replace(" ", "")

Use the split() method with subsequent join().

# Split the string by spaces and join without them
my_string = "Another string with spaces"
string_without_spaces = "".join(my_string.split())

Use regular expressions.

import re

# Remove all whitespace characters using regex
my_string = "  String\twith\nvarious  spaces  "
string_without_spaces = re.sub(r'\s+', '', my_string)

Comparison of methods:

Method	Description	When to use
replace(" ", "")	Removes only regular spaces.	A simple case when you need to remove only standard spaces.
"".join(str.split())	Removes sequences of spaces.	Convenient for removing multiple consecutive spaces.
re.sub(r'\s+', '', str)	Removes any whitespace characters (\s).	For removing spaces, tabs, newlines, etc.
