Does a module contain package or vice versa?
When we import something in Python, do we import a module or a package?

One question. So, we can import the entire package or just a module in a given

Is there a difference between functions and methods in Python.
For example, this is the text from tutorialpoint on Python:
Python includes the following list functions - cmp, len etc.
Python includes following list methods - append, count
