Delete digits in Python (Regex)

Question

I am trying to delete all digits from a string. However, the next code deletes as well digits contained in any word. Obviously, I don't want that. I have been trying many regular expressions with no success.

Thanks!

s = "This must not be deleted, but the number at the end yes 134411" s = re.sub("\d+", "", s) print s 

Result:

This must not b deleted, but the number at the end yes

Answer 1

Add a space before the \d+.

>>> s = "This must not b3 delet3d, but the number at the end yes 134411" >>> s = re.sub(" \d+", " ", s) >>> s 'This must not b3 delet3d, but the number at the end yes ' 

Edit: After looking at the comments, I decided to form a more complete answer. I think this accounts for all the cases.

s = re.sub("^\d+\s|\s\d+\s|\s\d+$", " ", s) 

Answer 2

Try this:

"\b\d+\b" 

That'll match only those digits that are not part of another word.
