尝试一下:

from re import sub
from decimal import Decimal

money = '$6,150,593.22'
value = Decimal(sub(r'[^\d.]', '', money))

这具有一些优点，因为它使用 Decimal 而不是float(这更适合表示货币)，并且通过不对特定货币符号进行硬编码来避免任何语言环境问题.

This has some advantages since it uses Decimal instead of float (which is better for representing currency) and it also avoids any locale issues by not hard-coding a specific currency symbol.
