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.
Hi everyone, I recently took the Fullstack Python Developer course and am now taking my first steps on this path.
Can you tell me what other methods of removing spaces from text you know and in which case, each of them is better to use?
So far I know 4 of them:
-
replace method -> text_wo_spaces = text.replace(" ","")
-
join and split methods -> text_wo_spaces = ' '.join(text.split())
-
list generator + join -> text_wo_spaces = ' '.join([char for char in text if char != ' '])
-
filter + join methods -> text_wo_spaces = ' '.join(filter(lambda char : != ' ', text))
Hello, I have a comment block that has the following format:
// # [some comment] // # [some comment] // # [some comment] // # [some comment]
Each line is stored in an array of strings. Is there a way for me to remove the whitespace between the slashed and hashtag?? (i.e. i would like for it to be //# [some words])
Any help would be appreciated!
