Python DATA TYPES:-         In python, every value has a datatypes. Everything is the object in python programming, datatypes are actually classes and variables are instances(object) of these classes.        1. Numeric         2. Boolean        3. Sequence type               1.Strings                2.List                3.Tuple        4. Set        5. Dictionaries.                                                                        NUMBERS(NUMERIC):-            In this numeric values are stores in variables which are immutable  (the values assigned to a variables can be changed).           *  Integers(int) ,float point numbers(float)  and complex numbers(complex) are involved in this.                      * type() function  used to know which class a variable or value belongs to .           * isinstance() function used to check if an object belongs to particular class or not.            * complex() function used to convert integers to complex       eg:-         1.               

Python VALUES :-      Basically values are the digits or letters used in python to perform certain task.      These values has different types:                       1.integer type(int)                               eg:-   2,5                       2.floating point type(float)                             eg:-    3.0,2.0                       3.string                             eg:-    hello everyone ! VARIABLES :-                Variable is the location in memory used to store some data (value) or simply,a name that refer    to value.             * The rules of representing a variable is same as writing identifiers.      * In python,we even don't have to declare the type of the variable,it will handle internally according to the type of value which we assigned to the variable.    VARIABLE ASSIGNMENT:-                          We use assignment operator(=) to assign a value to variable.           eg :- 1.   a=34                  #here a is a variable and 34 is a value(int) .  

WHY PYTHON?      *Basically python is general purpose ,high level,interpreted language .         *Very simple language to learn.      *It has best packages for AI,deep learning,machine learning etc...      *It also has very interactive frame work that is ipython notebook .      *Extensively used in industry  Features OF PYTHON:-                   *simplicity                    *open source language- free for everyone 👯👫                    *portability-code sharing much easier   💯                                     *Embeddable and extensible                   *interpreted line by line (CPU and Memory Management)                   *huge libraries (Numpy , Matplotlib , Scikit-learn)                   *object oriented PYTHON  KEYWORDS(🔑) :                               keywords are reserved words.                              In python, there are 35 keywords.                      # get all keywords in python                  >>> import keyword             >>> print(
