[SOLVED] How to efficiently split currency sign and number in one string without using a for loop or try statement

Issue

I have a string like '$200,000,000' or 'Yan300,000,000'

I want to split the currency and number, and output a tuple ('$', '200000000'), without ',' in the number string.

Currently I’m using the following script, which is working:

def splitCurrency(cur_str):
    cuttingIdx = 0
    for char in cur_str:
        try:
            int(char)
            break
        except ValueError:
            cuttingIdx = cuttingIdx + 1
    return (cur_str[0:cuttingIdx].strip(),
            cur_str[cuttingIdx:len(cur_str)].replace(',',''))

I want to avoid using for-loop and try-except for performance and readability. Any suggestions?

Solution

>>> import re
>>> string = 'YAN300,000,000'
>>> match = re.search(r'([\D]+)([\d,]+)', string)
>>> output = (match.group(1), match.group(2).replace(',',''))
>>> output
('YAN', '300000000')
