How to remove special characters except space from a file in python?

Question

I have a huge corpus of text (line by line) and I want to remove special characters but sustain the space and structure of the string.

hello? there A-Z-R_T(,**)         


        

Answer 1

I think nfn neil answer is great...but i would just add a simple regex to remove all no words character,however it will consider underscore as part of the word

print  re.sub(r'\W+', ' ', string)
>>> hello there A Z R_T world welcome to python
