In this section, you learned that:

• Builtin objects are all objects that are written inside the Python interpreter in C language.

• Builtin modules contain builtins objects.

• Some builtin objects are not immediately available in the global namespace. They are parts of a builtin module. To use those objects the module needs to be imported first. E.g.:

  import time
  time.sleep(5)

• A list of all builtin modules can be printed out with:

  import sys
  sys.builtin_module_names

• Standard libraries is a jargon that includes both builtin modules written in C and also modules written in Python.

• Standard libraries written in Python reside in the Python installation directory as .py files. You can find their directory path with sys.prefix.

• Packages are a collection of .py modules.

• Third-party libraries are packages or modules written by third-party persons (not the Python core development team).

• Third-party libraries can be installed from the terminal/command line:

  Windows:

  pip install pandas or use python -m pip install pandas if that doesn't work.

• Mac and Linux:

  pip3 install pandas or use python3 -m pip install pandas if that doesn't work.
