Python有效地将货币符号和数字拆分为一个字符串 [英] Python efficiently split currency sign and number in one string

问题描述

我有一个字符串，例如'$ 200,000,000'或'Yan300,000,000'

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

我想拆分货币和数字，并输出一个元组('$'，'200000000')，数字字符串中不包含'，'.

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

当前我正在使用以下脚本，该脚本正在运行:

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(',',''))

除性能和可读性外，我要避免使用for循环和try-try.有什么建议吗?

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

推荐答案

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