有没有一种简单的方法可以将 ISO 8601 持续时间转换为 timedelta？

我怎样才能转换ISO 8601 持续时间字符串 https://en.wikipedia.org/wiki/ISO_8601#Durations to datetime.timedelta https://docs.python.org/3/library/datetime.html#datetime.timedelta?

我尝试只是实例化timedelta带有持续时间字符串和格式字符串，但我得到一个例外：

>>> from datetime import timedelta
>>> timedelta("PT1H5M26S", "T%H%M%S")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported type for timedelta seconds component: str

_{For the reverse, see Convert a datetime.timedelta into ISO 8601 duration in Python? https://stackoverflow.com/questions/27168175.}

I found isodate https://pypi.python.org/pypi/isodate图书馆做我想做的事

isodate.parse_duration('PT1H5M26S')
