由于冬季时间更改 pytz 导致时区转换失败

问：

在我的代码中，我尝试将日期转换为 pytz 时区，但由于凌晨 3 点更改为冬季时间，我的代码崩溃了。我有两个问题：第一，为什么更改时间会导致时区转换崩溃？二、如何避免这个bug？ 这是我的代码：

purchase_date = make_aware(
    datetime.strptime(
        sale.findtext('n:purchasedate', namespaces={'n': ns}),
        '%d/%m/%Y-%H:%M'
    ),
    timezone('Europe/Paris')
)

返回错误：

Traceback (most recent call last):
  File "/app/manage.py", line 15, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python3.11/site-packages/django/core/management/__init__.py", line 442, in execute_from_command_line

知道我的代码是在凌晨 3：02 执行的，而时间的变化发生在凌晨 3：00。

提前感谢您的任何回复！
