Python 2, use raw_input:

raw_input

name = raw_input(' Enter name: ')


Python 2's input function is basically Python 3's eval(input(..))

input

eval(input(..))

Python 3, python 2's input is removed,

input

Only keeping raw_input which is renamed to input

raw_input

input

In Python 2.x, input tries to evaluate the input as a Python expression. You want to use the raw_input function instead:

input

raw_input

# input('...') is equivalent to eval(raw_input('...'))
name = raw_input(' Enter name: ')


However, if you are just starting out, you should be using Python 3, where the input function behaves like Python 2's raw_input function. (There is no function that automatically tries to evaluate the string; it was considered a bad design choice to provide such a function.)

input

raw_input
