New submission from ArtOfCode Studio <artofcodestu...@gmail.com>:
I want to find all imported modules in a python program. I am using the
``modulefinder`` standard module for my job. I am trying to follow [this
example](https://docs.python.org/3.8/library/modulefinder.html#example-usage-of-modulefinder)
on docs, but I get this error even if I use the same code as the documents:
````python

````
My operating system is Windows 10.
I am using Python3.8.1
If there is a better way of finding imported modules let me know it.
Also is there any way of saying that to Python: "use unicode for directory
names"?
