built in python modules and their uses

11.  abc				- This tiny module delivers the environment you need for creating abstract base classes
22.  argparse		- This module contains tools that make it easier to create user-friendly interfaces from the level of the command line
33.  asyncio			- This is a very large module that delivers the framework and environment for asynchronous programming
44.  base64			- This well-known module delivers a tool for coding and decoding binary code into a format that can be displayed – and 
5					  the other way round
65.  collections		- This module offers specialized container data types that work as an alternative to basic contained types for general
7					  purposes such as dict, list, set, and tuple.
86.  copy			- Everyone uses this tiny module that contains tools for deep copying of container type data. Its most famous function is `deepcopy` – if not for this function, copying lists and dictionaries would become a torture for developers.
97.  csv				- Delivers functionalities for exporting and importing tabular data in CSV format. The module allows developers to say “load data” or “save data” from to a CSV file.
108.  datetime		- It delivers tools that make it easier to work with dates and times
119.  decimal 		- The module delivers a data type called Decimal. Its main advantage is correct rounding of decimal numbers which is extremely important in billing systems– even
12					  a slight distortion with several hundred thousand operations can change the final result significantly
1310. functools		- The functools module comes in handy for higher-order functions, ie. the functions that act on or return other functions. You can treat any callable 
14					  object as a function for the purposes of this module.
1511. hashlib			- his handy module implements a common interface to numerous secure hash and message digest algorithms like the FIPS 
16					  secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512
1712. http			- his package collects several modules for working with the HyperText Transfer Protocol 
1813. importlib 		- The package provides the implementation of the import statement (and the __import__() function) in Python source code
1914. itertools		- This useful module implements iterator building blocks inspired by constructs 
20					  from APL, Haskell, and SML (all in a form that matches Python programs)
2115. inspect 		- The module offers several useful functions that help developers get information about live objects such as 
22					  modules, classes, methods, functions, tracebacks, frame objects, and code objects in Python code
2316. json			- Helps to work with json data
2417. logging			- This module defines functions and classes that provide a flexible event logging system for applications and libraries
2518. math			- This module gives developers access to the mathematical functions defined by the C standard
2619. multiprocessing	- This handy package supports spawning processes with the help of an API similar to the threading module
2720. os				- Offers a portable method of using operating system dependent functionality.
2821. pdb				- This module defines an interactive source code debugger
2922. random			- pseudo-random number generators for various distributions
3023. re				- Provides regular expression matching operations similar to those you get in Perl
3124. shutil			- Provides a number of high-level operations on files and collections of files, especially functions that 
32					  support file copying and removal
3325. sys				- offers access to variables used or maintained by the interpreter and functions that interact strongly 
34					  with the interpreter
3526. threading		- This useful module builds higher-level threading interfaces on top of the lower level _thread module
3627. types			- It defines names for object types used by the standard Python interpreter but not exposed as builtins
3728. unittest		- Works similarly to major unit testing frameworks in other programming languages
3829. urllib			- This handy package collects several modules for working with URLs
3930. uuid			- The module provides immutable UUID objects, as well as the following functions for generating version 1, 3, 4, and 5 UUIDs
