What's the difference between `raw_input()` and `input()` in Python 3?

Question

What is the difference between raw_input() and input() in Python 3?

Answer 1

In Python 3, raw_input() doesn't exist which was already mentioned by Sven.

In Python 2, the input() function evaluates your input.

Example:

name = input("what is your name ?")
what is your name ?harsha

Traceback (most recent call last):
  File "", line 1, in 
    name = input("what is your name ?")
  File "", line 1, in 
NameError: name 'harsha' is not defined

In the example above, Python 2.x is trying to evaluate harsha as a variable rather than a string. To avoid that, we can use double quotes around our input like "harsha":

>>> name = input("what is your name?")
what is your name?"harsha"
>>> print(name)
harsha

raw_input()

The raw_input()` function doesn't evaluate, it will just read whatever you enter.

Example:

name = raw_input("what is your name ?")
what is your name ?harsha
>>> name
'harsha'

Example:

 name = eval(raw_input("what is your name?"))
what is your name?harsha

Traceback (most recent call last):
  File "", line 1, in 
    name = eval(raw_input("what is your name?"))
  File "", line 1, in 
NameError: name 'harsha' is not defined

In example above, I was just trying to evaluate the user input with the eval function.
