trying to recall a regex for re.split()

[Gribouillis]

I draw my 20 years old regex for floating numbers

import re

def float_re():
    "Retourne une expression régulière qui matche les nombres flottants littéraux"
    return r"[+-]? *(?:\d+(?:\.\d*)?|\.\d+)(?:[eE][+-]?\d+)?"

pat = re.compile(float_re())

def parse(s):
    mo = pat.match(s)
    if mo:
        return (float(mo.group(0)), s[mo.end():].strip())
    else:
        raise ValueError(
            'Expected string starting with a literal float, got', s)

if __name__ == '__main__':
    a = ['144mHz','432 mHz','1.296GHz','2.304 GHz']
    for s in a:
        print(repr(s), parse(s))

Output:
'144mHz' (144.0, 'mHz')
'432 mHz' (432.0, 'mHz')
'1.296GHz' (1.296, 'GHz')
'2.304 GHz' (2.304, 'GHz')
