python中根据字符串导入模块module

需要导入importlib，使用其中的import_module方法

import importlib
modname = &#39;datetime&#39;
datetime_module = importlib.import_module(modname)
print(datetime_module)
# <module &#39;datetime&#39; from &#39;C:\\Users\\huchengyue\\AppData\\Local\\Programs\\Python\\Python37\\lib\\datetime.py&#39;>
obj = getattr(datetime_module,&#39;datetime&#39;)
print(obj.now())
# 2019-03-05 23:25:16.077121
print(dir(datetime_module))
# [&#39;MAXYEAR&#39;, &#39;MINYEAR&#39;, &#39;__builtins__&#39;, &#39;__cached__&#39;, &#39;__doc__&#39;, &#39;__file__&#39;, &#39;__loader__&#39;, &#39;__name__&#39;, &#39;__package__&#39;, &#39;__spec__&#39;, &#39;date&#39;, &#39;datetime&#39;, &#39;datetime_CAPI&#39;, &#39;time&#39;, &#39;timedelta&#39;, &#39;timezone&#39;, &#39;tzinfo&#39;]

输出datetime_module即为module对象datetime。
