Printing on screen

Like every programming language python also provides us with two inbuilt functions:-

  1. raw_input(prompt)
  2. input(prompt)

raw_input()-It reads the input or command and returns a string. This means, even when the user inputs an integer value, it will still be considered as a string. This inbuilt function can only be used in Python 2.x and not in Python 3.x.

input()-Reads the input and returns a python type like list, tuple, int, etc. This means if the user enters an integer, an integer will be returned and if the user enters a string, a string will be returned.

The input() method takes a single optional argument:

prompt(optional) – a string that is written to standard output(usually screen) without trailing newline.

This is how it works in Python 2.x versions whereas in Python 3.x versions, input() always returns a string and this function is just a replacement of raw_input() function.

How does the input function work in python?

How does the input function work in python?

The Python compiler reads the code from top to bottom. So whenever it finds an input function written this way input(“prompt”), it stops and displays the prompt message. Then, it waits for the user to enter the input value and then proceeds.


a=input("Enter your name:")
output - Enter your name: Python

Return value from input()

The input() method reads a line from the input (usually from the user), converts the line into a string by removing the trailing newline, and returns it.

If EOF is read, it raises an EOFerror exception.

Input using input function()

Input() function lets you ask the user for some text input. You call this function to tell the program to stop and wait for the user to key in data. The program will resume once the user presses the ENTER or RETURN key.


The print() function prints the given object to the standard output device screen.


print(objects, separator=' ', end='\n', file=sys.stdout)

Objects- The object that is to be printed.
Separator- If there are more than one object than it is separated by separator.
End- End is printed at last.


print("Python is one of the most famous programming language.")

This is all about printing on screen in python.
