User input is an important part of Python applications. The
input() function can be used to get user input interactively in Python scripts and applications. The input() function simply reads the user input via the standard input and returns the value which is generally assigned to a string variable.
input() Function Syntax
The input() function has the following syntax. The input() function returns the input value as string type.
- MESSAGE is the message which is displayed before the user input.
input() Function Example
In the following example, we get user input for the username. The input value is assigned into the
name a variable which is a string.
name = input("Please enter your name:") print("Your name is ",name)
Your name is İsmail
Convert User Input
As a generic type user input is returned as a string. But in some cases, this may not be the result we expect. We can convert the user input into other types like integers. In the following example, we request the age information and convert provided age value into an integer with the
i = input("Please enter your age:") age = int(i) print("You will be ",age+20," after 20 years.")
You will be 58 after 20 years.
Input Multiple Items As List
Another use case for the input() function is the ability to get multiple items with a single input. The input values can be converted into a list easily by using the
split() . In the following example, we provide “ahmet ali baydan” as input and split it according to spaces.
l = input("test:").split() print(l)
['ahmet', 'ali', 'baydan']
