text - Differences between input commands in Python 2.x and 3.x

Question

Ok, so i use a lot of input commands, and I understood that in Python2 I can do:

text = raw_input ('Text here')

But now that i use Python 3 I was wondering what's the difference between:

text = input('Text here')

and:

text = eval(input('Text here'))

when do I have to use the one or the other?

Answer 1

In Python 3.x, raw_input became input and Python 2.x's input was removed. So, by doing this in 3.x:

text = input('Text here')

you are basically doing this in 2.x:

text = raw_input('Text here')

Doing this in 3.x:

text = eval(input('Text here'))

is the same as doing this in 2.x:

text = input('Text here')

Here is a quick summary from the Python Docs:

PEP 3111: raw_input() was renamed to input(). That is, the new input() function reads a line from sys.stdin and returns it with the trailing newline stripped. It raises EOFError if the input is terminated prematurely. To get the old behavior of input(), use eval(input()).
