How to compare strings that have spaces - hobbyist - Jan-14-2021
I want to compare two strings and check if they are the same. For example, this string:
"This is a sentence"
with this:
" This is a sentence "
As can be seen they are not to the same since the last sentence has before and after the sentence spaces. How do I do this kind of comparisons?

Use the strip() method
if string1.strip() == string2.strip():
do_something()If you also want to take into account the inner spaces, you can achieve this with the re module>>> import re >>> a = "This is a sentence\t that says foo bar " >>> b = " This is a sentence that says foo\t bar" >>> >>> def norm(s): ... return re.sub(r"\s+", " ", s.strip()) ... >>> norm(a) 'This is a sentence that says foo bar' >>> norm(b) 'This is a sentence that says foo bar' >>> norm(a) == norm(b) True >>> a == b False >>>

What appears to be a problem? As you stated, they are not the same and simple string comparison with
== will confirm it and return False.
