From each word, using regular expressions, the part without punctuation is extracted, which is reversed and replaced

import re

inp = 'I love my country! It is @beautiful'
out = []

for w in inp.split(' '):
    sw = re.search(r'[a-zA-Z]+', w)[0]
    out.append(w.replace(sw, sw[::-1]))
print(' '.join(out))

Prints:

I evol ym yrtnuoc! tI si @lufituaeb

  • The solution assumed that punctuation is always at the boundary (or kind of), `co#untry!` --> `oc#untry!` – cards Sep 05 '22 at 21:23

Oneliner:

import re
text = 'I love my country! It is @beautiful'
''.join([ s[::-1] for s in re.split(r'(\W)', text)])

Results in:

'I evol ym yrtnuoc! tI si @lufituaeb'

  • if punctuation not at the boundary of a word then the reversion is local (partition-like effect)l, `co#untry!` --> `oc#yrtnu!`. Also if the question doesn't provide enough information it could also be `yr#tnuoc!` – cards Sep 05 '22 at 21:20
