What is the difference between raw_input() and input() in Python 3?
754
Basically, the difference between raw_input and input is that the return type of raw_input is always string, while the return type of input need not be string only. Python will judge as to what data type will it fit the best. In case you have entered a number, it will take it as an integer.
Python raw_input function is used to get the values from the user. We call this function to tell the program to stop and wait for the user to input the values. It is a built-in function. The input function is used only in Python 2. x version.
Python 3 – input() function. In Python, we use input() function to take input from the user. Whatever you enter as input, the input function converts it into a string. If you enter an integer value still input() function convert it into a string.
The NameError: name 'raw_input' is not defined occurs when you try to call the raw_input() function using Python major version 3. You can only use raw_input() in Python 2. To solve this error, replace all instances of raw_input() with the input() function in your program.
The difference is that raw_input() does not exist in Python 3.x, while input() does. Actually, the old raw_input() has been renamed to input(), and the old input() is gone, but can easily be simulated by using eval(input()). (Remember that eval() is evil. Try to use safer ways of parsing your input if possible.)
