如何在Python中将带分数的字符串转换为浮点数 [英] How to convert string with fraction to float in Python

问题描述

我正在准备一些要插入MySQL的数据.不幸的是，某些数据的格式为100½.我需要将其转换为浮点数，但显然 float(100½)失败.

I'm prepping some data to insert into MySQL. Unfortunately some of the data is in the form 100½. I need to convert this to a float, but obviously float(100½) fails.

Python中是否有一种方法可以处理此转换?我不反对对某些东西进行硬编码，但将来可能会遇到⅝或其他分数.

Is there a method in Python that can handle this conversion? I'm not opposed to hard coding something, but I may encounter ⅝ or other fractions in the future.

推荐答案

>>> float(sum(fractions.Fraction(x) for x in unidecode.unidecode('100½').split()))
100.5

分数
