How to convert a negative number stored as string to a float?

我在Python 3.6上遇到此错误，却不知道如何克服它.

Am getting this error on Python 3.6 and don't know how to get over it.

>>> s = '–1123.04'
>>> float(s)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: could not convert string to float: '–1123.04'

推荐答案

您的字符串包含一个Unicode破折号，而不是ASCII连字符.您可以替换它:

Your string contains a unicode en-dash, not an ASCII hyphen. You could replace it:

>>> float('–1123.04'.replace('\U00002013', '-'))
-1123.04
