In Python, I have a list like
["HELLO MR GOOD SOUL"]. How can I replace multiple spaces with a single space, to get
["HELLO MR GOOD SOUL"]?
You can use
re.sub with a regular expression for this:
s = "HELLO MR GOOD SOUL" re.sub(r"\s+", " ", s)
\s is whitespace,
+ means one or more. Since Regex is greedy by default, the pattern
\s+ will match as many consecutive spaces as possible.
'HELLO MR GOOD SOUL'
If you actually have a list of strings, you can do a simple list comprehension:
list_of_strings = [...] [re.sub(r"\s+", " ", s) for s in list_of_strings]
If you want to do it in-place:
for idx, s in enumerate(list_of_strings): list_of_strings[idx] = re.sub(r"\s+", " ", s)
