python string remove whitespace

stackoverflow.com › questions › 8270092 › remove-all-whitespace-in-a-string

If you want to remove leading and ending whitespace, use str.strip():

>>> "  hello  apple  ".strip()
'hello  apple'

If you want to remove all space characters, use str.replace() (NB this only removes the “normal” ASCII space character ' ' U+0020 but not any other whitespace):

>>> "  hello  apple  ".replace(" ", "")
'helloapple'

If you want to remove all whitespace and then leave a single space character between words, use str.split() followed by str.join():

>>> " ".join("  hello  apple  ".split())
'hello apple'

If you want to remove all whitespace then change the above leading " " to "":

>>> "".join("  hello  apple  ".split())
'helloapple'

To remove only spaces use str.replace:

sentence = sentence.replace(' ', '')

To remove all whitespace characters (space, tab, newline, and so on) you can use split then join:

sentence = ''.join(sentence.split())

or a regular expression:

import re
pattern = re.compile(r'\s+')
sentence = re.sub(pattern, '', sentence)

If you want to only remove whitespace from the beginning and end you can use strip:

sentence = sentence.strip()

You can also use lstrip to remove whitespace only from the beginning of the string, and rstrip to remove whitespace from the end of the string.

Strip Command doesn't remove white space of a string stored in a variable

I tried to use the .strip() command to eliminate white spaces from a string variable and then print it. The white spaces were not removed. Can someone explain why the strip() command isn’t working where I’m going wrong and what is the right way to use this command? More on discuss.python.org

You are missing a regex. And the best one is number 1. Because of readability. Plus numbers 2, 3 and 4 don't work. You are putting the space back. More on reddit.com
