Answer 1

This function handles float and negative numbers as well.

def separate_number_chars(s):
    res = re.split('([-+]?\d+\.\d+)|([-+]?\d+)', s.strip())
    res_f = [r.strip() for r in res if r is not None and r.strip() != '']
    return res_f

For example:

utils.separate_number_chars('-12.1grams')
> ['-12.1', 'grams']
