How to remove special characters from string except space in Python

By Mohammed Abualrob Code Snippets 0 Comments

Problem

Given an input string, provide Python code to remove all special characters except spaces.

Solution

This is a typical regular expressions question. Please find the answer below..

Code

The idea is to match only letters, spaces and exclude everything else. Take a look…

# Import regular expressions module
import re

# Example input string
string = "[~How! @are# $you% ^doing& *today\(). _I- +hope=| <everything> `is~ {fine}]"

# Only keep:
# Letters a-z, A-Z
# Dots (.)
# Numbers (\d)
# Non white space (\s)
# ^ means other than the provided patterns
# need to be substituted by an empty string
string = re.sub('[^a-zA-Z.\d\s]', '', string)

# Print the final string. This should print:
# How are you doing today. I hope everything is fine
print(string)

# Import regular expressions module

import re

# Example input string

string = "[~How! @are# $you% ^doing& *today\(). _I- +hope=| <everything> `is~ {fine}]"

# Only keep:

# Letters a-z, A-Z

# Dots (.)

# Numbers (\d)

# Non white space (\s)

# ^ means other than the provided patterns

# need to be substituted by an empty string

string = re.sub('[^a-zA-Z.\d\s]', '', string)

# Print the final string. This should print:

# How are you doing today. I hope everything is fine

print(string)
