如何在Python3中列出导入的模块和版本 [英] How to list imported modules and version in Python3

问题描述

我知道有几个关于SO的问题似乎可以解决此问题(例如此).但是，报告的解决方案似乎在我的代码(python 3.6.5)中不起作用.在第一种情况下，打印的模块较少，在第二种情况下，显示的信息更多(sys.modules.keys()).

I am aware that several questions on SO seem to address this problem (e.g. this, this). However, the reported solution seem not to work in my code (python 3.6.5). In the first case, fewer modules are printed, in the second case a lot more information is displayed (sys.modules.keys()).

是否有一种简便的方法，可以以与sessionInfo()类似的方式在__version__)(通过__version__) "rel =" nofollow noreferrer> R ?

Is there an easy way to display all imported top modules together with versions (through __version__) in a similar fashion as sessionInfo() in R?

推荐答案

这对我有用:

import sys
for module in sys.modules:
    try:
        print(module,sys.modules[module].__version__)
    except:
        try:
            if  type(modules[module].version) is str:
                print(module,sys.modules[module].version)
            else:
                print(module,sys.modules[module].version())
        except:
            try:
                print(module,sys.modules[module].VERSION)
            except:
                pass
