如何在 Python 中将货币字符串转换为浮点数?
问题描述
我有一些字符串表示特定货币格式的数字，例如:
I have some strings representing numbers with specific currency format, for example:
money="$6,150,593.22"
我想把这个字符串转换成数字
I want to convert this string into the number
6150593.22
实现这一目标的最佳方法是什么?
What is the best way to achieve this?
解决方案
试试这个:
from re import sub
from decimal import Decimal
money = '$6,150,593.22'
value = Decimal(sub(r'[^d.]', '', money))
这有一些优点，因为它使用 Decimal 而不是 float(更适合表示货币)并且它还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.
