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 ðŸ’¯                 
                  *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.  

               Python Variable Names and Keywords - MAKE ME ANALYST
 
#get all keywords in python 
   

            >>> import keyword
            >>> print(keyword.kwlist)    #kwlist is just like holding elements in list


  
output:-['False', 'None', 'True', 'and', 'as', 'assert', 'async', 'await', 'break', 'class', 'continue',
               'def', 'del', 'elif', 'else', 'except', 'finally',  'for','from', 'global', 'if', 'import', 'in', 'is',
               'lambda', 'nolocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 'while', 'with', 'yield']

IDENTifiers  :-

        Identifiers is the name given to any entities like variables,functions,class etc..in python.

 Some rules to write identifiers:

     1.combinations of lowercase letters(a to z)or uppercase letters(A to Z)or digits(0 to 9)or                               underscore(_).
        eg:- abc_12     #valid

     2.identifiers cant start with digits
         eg:-  17_level   #invalid
               level_12  #valid

     3.keywords are not used as identifiers
         eg:-  global=23  #invalid (global is keyword in python)

     4.we cant use special symbols in identifiers like @,!,%
         eg:-  level@=24  #invalid

Python3 File Handling

-
Python  File Handling FILE  I/O          File is a named location on disk to store related information. It is used to store data permanently in a non-volatile memory (eg. hard disk).  Since, random access memory (RAM) is volatile which loses its data when computer is turned off ,we use files for the future use of the data    When we want to read from or write to a file we need to open it first. When we are done, it needs to be closed, so that resources that are tied with the file are freed.  File operation :   1.  Open a file   2.  Read or write(perform operation)   3.  Close the file Opening a File        Python has a built-in function open() to open a file. This function returns a file object, also called a handle, as it is used to read or modify the file accordingly.        #open file in current directory            f=open('example...
