Python Standard input and output


STANDARD INPUT AND OUTPUT

Python Output :
             We use the print() function to output data to the standard output devices.
        
  eg:     
              print("HELLO WORLD")
 
       output:  HELLO WORLD

  eg:       a=20
              print("The value of a is ",a)
              print("The value of a is "+ str(a))

       output:  The value of a is 20
                      The value of a is 20
 
OUTPUT FORMATING :

  eg:     a=10;b=30
            print("The value of a is {} and b is{}".format(a, b))

       output:  The value of a is 10 and b is 30
 
  eg:      a=10;b=30
             print("The value of b is {1} and a is {0}".format(a, b))

       output:   The value of b is 30 and a is 10

 
  eg:        print("Hello {name},{greeting}".format(name="Suma", greeting="Good Morning"))

       output:   Hello Suma, Good Morning


  eg:         print("the story of {0},{1} ,and {other}" .format('Bill', 'Manfred', other= 'George'))

       output:   the story of bill, Manfred and George

PYTHON INPUT :
                If we want to take the input from the user ,we use input() function to allow this

eg:       num=input("enter a number:")
            print(num)

       output:    enter a number:4
                        4

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.txt')          we can specify the mode while opening a file. In mode, we specify whether we want to read 'r' , write 'w' or appen

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(
