Question

I have strings like

uint8_t
char[5]
int[3]

How can I write a short function to get the type and length separately in an elegant way

for eg

uint8_t // return 'uint8_t', '1'
char[5] // return 'char', '5'
...

Answer 1

Let’s make it a one-liner:

import re

def type_and_size(s):
    return re.split('[][]', s+'[1]', 2)[:2]

type_and_size('char')
['char', '1']

type_and_size('char[5]')
['char', '5']

Obviously you can do:

type, size = type_and_size('char[5]')
