Using a module with variable name in Python [duplicate]

Question

I want to run a function of a module with a variable name for example:

Plugins.SomeUnknownName.function() without knowing their name but Plugins. and .function() stay the same.

I have tried several things like plugin = 'Plugins.' + unknown_plugin_name + '.function()' or

plugin_name = "SomePlugin"

Plugins.plugin_name.function()

But I don't know any further.

Maybe someone knows how to solve that.

Also this is my first stack overflow post, so please correct me if I did something wrong.

You can use getattr to pass the string name. Using numpy as an example here's what the normal usage would look like

>>> import numpy
>>> numpy.random.randint(1, 5)
2

Now similar to your example

>>> getattr(numpy, 'random').randint(1, 5)
2

So applying to your case

getattr(Plugins, 'plugin_name').function()
