For example, if there is an infinite loop in the script that will terminate based on specific user input, then it will wait for the input from the user in each iteration of the loop. Sometimes, it requires waiting or pause the input task for a specific period of time for programming purposes. Both of these function are used to get the input from the user.Input() method is used in python 3 for data intake from the user. In python there are two function to get the input from the user that is input and raw_input function.

Let us see how to use input and raw_input function in Python.While in python 3 input() returns a string but can be converted to any type. In python 2, raw_input() returns a string whereas input() return result of an evaluation.In python 2, the input() function was used first to take raw_input() and then performing an eval() in it.The raw_input function work in the same way as the input function in python3.The raw_input function was built in python 2.Let us discuss the difference between input() and raw_input() function in python. You can see the below output.Ģ0564 Difference between input() and raw_input() function in python Once you will print “value” then you will get the variable and its type. Here, the value “20564” is taken from the user but we have converted the type to an integer using int(). Here, in python2 we will see if we want the output in integer then, we have to convert the type to an integer using “int” in raw_input() function.Įxample: value = raw_input('Enter the roll: ') The type of value stored is always string for raw_input() function. In the output, you can see its type is a string. The raw_input() function is similar to input() function in python3.Įxample: Program in python2 value = raw_input('Enter your name: ')

The first one is input and the second is the raw_input function. Python 2.x has two functions to take the value from the user. This input function is used only in the Python 2.x version. Python raw_input() function reads the input and returns a string. Python input() function Python raw_input() function You can refer to the below screenshot python input() function We don’t need to explicitly change the variable type in python2.

Here, it asks the user to enter the value, and then it reads the input and returns the type of input the user entered.

It reads the input and returns the python type like int, list, tuple, etc.Įxample: Program in python2 value = input('Enter your name:')Īfter writing the above code (python input() function), Ones you will print “ value ” then the output will appear as a “Enter your name: Naisha Naisha “. This function is called to tell the program to stop and wait for the user to input the values. The python input() function takes the value from the user. We use input() and raw_input() function to accept the user inputs according to their own value. It makes the code interactive instead of hard coding. The main reason is the user-friendly code which is interactive. Python NameError: name raw_input not defined Why we need input() and raw_input() function in python?
