Where to keep local Python modules?

This isn't a question about how to set PYTHONPATH so that Python code can find imported modules, it's about what is a sensible layout for one's home directory - i.e. where to put Python modules. I'm running Linux and have a number of Python modules that are only used by my own code. My top level

Re: Why the list creates in two different ways? Does it cause by the mutability of its elements? Where the Python document explains it?

that, though. Normally you should compare tuples using '==', not 'is'. Exceptions to this usually involve something like cacheing where identity is only used for optimisation purposes, and the end result doesn't depend in it. I mean if I use a tuple in a set or as the key in a dictionary and a second one

RE: Why the list creates in two different ways? Does it cause by the mutability of its elements? Where the Python document explains it?

have a lazy evaluation where things are not even copied when doing some things and only copied if absolutely needed as in when you make a change. So you can create say a data.frame then make another from it with some columns added and removed and the storage used does not change much, but add
