Removing any single letter on a string in python

Question

I would like to remove any single letter from a string in python.

For example:

input: \'z 23rwqw a 34qf34 h 343fsdfd\'
output: \'23rwqw 34qf34 343fsd         


        

Answer 1

import re
text = "z 23rwqw a 34qf34 h 343fsdfd"
print re.sub(r'(?:^| )\w(?:$| )', ' ', text).strip()

or

tmp = re.sub(r'\b\w\b', ' ', input)
print re.sub(r'\s{2,}', ' ', tmp).strip()
