Input in Python

When software developers work on a particular project, they often need to interact with the users. The most common purposes of these interactions are to either get some information or represent the results. 

Majorities of the programs use a dialog box that asks the users to offer some inputs. However, the case is different for Python. Python comes up with an inbuilt function called input in Python. With this function, one can read the inputs from the keyboard itself. 

Want more clarity on this? This article will offer you some unique examples of input in Python and cover the following topics relating to the input function in python;’

  • What is the input() function?
  • Why is the input in Python required?
  • How does the input() function in Python work

What Is the Input() Function? Explain With Some Examples 

This function i.e. input in Python takes any input from the users. Later on, it evaluates this expression. Python can automatically identify whether or not a user has inserted a number list or a string. If you have entered a wrong input, it’s either a syntax error or an exception that Python has raised. 

The syntax of input in Python is - input([prompt]) 

Whichever value you are entering as the input, the input in Python will convert it into a string. This is true for an integer value as well. In that case, you’ll have to explicitly convert it into an integer within your code itself through typecasting. 

Refer to the below examples to understand input in Python properly. 

Example 1: Get a User Input Without Prompt 

#Using input() function without prompt

Input = input()

print('The string which has been given is :', Input)

The output is as follows:

inputwithoutprompt

Example 2: Get a User Input With Prompt

#Using input() function with at prompt

Input = input(‘What is your name?’)

print('Hello, ', Input)

The output is as follows: 

inputwithoutprompt2

What Is the Need for Input() Function? 

Wondering why input in Python is important? Here’s why: 

  • Software developers may have to communicate with the users 
  • Most programs add a dialogue box to collect the inputs from users 
  • The input in Python is a way to read different inputs from the keyboard 

How Does the Input() Function Work? 

Find out how the input function in Python works, below: 

  • When the input() function is in the process of execution, the flow of a program will be stopped until the user has provided an input 
  • The message you can view on the output screen to ask a user for input values is optional. This means that the prompt that gets printed on the screen is optional
  • You should also remember that any input you’re inserting will be converted into a string
