In previous article we read about what is  basics of python and what are data types in Python? Today I am going to learn that how to write a interactive & charming program by using input() & print() function.

In this article we learn about that how we take input data from the user & then display on the screen. Here we use mainly two function as 

(i) Input() 

(ii) Print() 



(i) Input() 

To get the user's input data simply we use input function. Example -  

userName=input("Please Enter your Name:") 

You asked from user that 'Please enter you name' user will entered self name. If you want to any other input from user you can find them from using the input function. 

(ii) Print() 

The print() function is used to display the information of users, which have entered by using the input function. 

It accepts zero or more expressions as parameters, separated by commas.

Now you can use the print function such as

print("Hey There! My name is: ", userName)

Note - userName will print that value which value stored by the user in input() function. 

Then after save the file and run the program you will find that a message will display on screen that (Please Enter Your Name:) suppose user entered his name Ram, then after press the enter button you will find this output that

Hey There! My name is Ram.

Triple Quotes -

If you need to display a long message, you can use the triple-quote symbol (' ' 'or' ' ' ) to span your message over multiple lines.

Example - 

print ('''Hello World.

My name is James and I am 20 years old.’’’)

Output of this code is

Hello World.

My name is James and I am 20 years old.
