Is there a simpler way in python

Question

I did the following to get from P13 to {P}{13}

import re

txt  = "P13"
x = re.search("[A-T]", txt )
y = re.split("[A-T]", txt )
txt  = "{" + x.group() + "}" + "{" + y[1] + "}"

It is working and gives what I want. But I'm wondering if there's an easier way.

Answer 1

You can try regex replace

out = re.sub('([A-T]+)(\d+)', r'{\1}{\2}', txt)

$ print(out)

{P}{13}

Explanation:

• 1st Capturing Group ([A-T]+)

  Match a single character present in the list [A-T] one and unlimited times

• 2nd Capturing Group (\d+)

  \d matches a digit (equivalent to [0-9]) and + matches the previous token between one and unlimited times
