Python Collections (Arrays)
There are four collection data types in the Python programming language:
List is a collection which is ordered and changeable. Allows duplicate members.
Tuple is a collection which is ordered and unchangeable. Allows duplicate members.
Set is a collection which is unordered, unchangeable*, and unindexed. No duplicate members.
Dictionary is a collection which is ordered** and changeable. No duplicate members.
*Set items are unchangeable, but you can remove and/or add items whenever you like.
**As of Python version 3.7, dictionaries are ordered. In Python 3.6 and earlier, dictionaries are unordered.
When choosing a collection type, it is useful to understand the properties of that type. Choosing the right type for a particular data set could mean retention of meaning, and, it could mean an increase in efficiency or security.

توضیحاتی درباره‌ی PIP:
Link: https://www.w3schools.com/python/python_pip.asp

خلاصه:
دستور نگاه کردن نسخه pip:
pip --version

دستور نصب پکیج:
pip install "package name"

دستور حذف پکیج:
pip uninstall "package name"

دستور دیدن فهرست پکیج های نصب شده:
pip list

پ.ن: قاعدتاً وقتی شما دستور pip list رو میزنید با اسم setuptools هم مواجه میشید که احتمالاً نمی‌دونید چی هست و از کجا اومده.
در پایین توضیح داده شده که setuptools چی هست.

setuptools is a package used by many other packages to handle their installation from source code (and tasks related to it).

It is generally used extensively for non-pure-Python packages, which need some compilation/installation step before being usable (think packages containing extensions written in C); setuptools factors away some of the most common operations used in this process (compiling C files with options compatible with the current Python installation, running Cython if required, provide some vaguely coherent set of commands/options for setup.py files, ...) as well as providing some tools used during Python packages development.
