How To Remove Large Amounts Of White Space From A Python String?

I know there are a few similar questions to mine but I couldn't find a solution for my problem. I have a string which is: 'subject: Exercise Feedback Form persona_id: bresse Q1: Ye

Solution 1:

you could use regular expressions and configure the expression to replace n or more spaces/newline/tabs/blanks by one single space:

import re

s ="hello     \n   world"print(re.sub("\s{4,}"," ",s))

prints:

hello world

here it will remove all blanks/newlines/tabs/whatever (\s in regex) if there are at least 4 of them, and will replace only by one space (to avoid that words that were separated are collated after the replacement, you can replace that by a newline or no character).

Solution 2:

Where's text is your string:

import re
text = re.sub(r"\s{2,}", "", text)

Solution 3:

try this:

s = """subject: Exercise Feedback Form
persona_id: bresse
Q1: Yes
Q1 comments: Yes everything was found A1
Q2: No
Q2 comments: No forgot to email me A2
Q3: Yes
Q3 comments: All was good A3
Q4: No
Q4 comments: It was terrible A4
Q5_comments: Get Alex to make it better






























subject: Issue With App
persona_id: bresse
comments: Facebook does not work comments feedback"""
s = s.replace("\n\n","")
print(s)

Solution 4:

You can use re.sub:

import re
print(re.sub('(?<=\n)\s+\n', '', content))

Output:

"subject: Exercise Feedback Form
persona_id: bresse
Q1: Yes
Q1 comments: Yes everything was found A1
Q2: No
Q2 comments: No forgot to email me A2
Q3: Yes
Q3 comments: All was good A3
Q4: No
Q4 comments: It was terrible A4
Q5_comments: Get Alex to make it better
subject: Issue With App
persona_id: bresse
comments: Facebook does not work comments feedback"

Solution 5:

Without using re :

Removing useless spaces :

' '.join(text.split())

Removing useless \n :

'\n'.join(filter(None, text.split('\n')))
