• input() (Python 3):
  • Reads a line from input, converts it to a string, and returns it.
• raw_input() (Python 2):
  • Reads a line from input and returns it as a string (no conversion).
  • raw_input() was renamed to input() in Python 3, and the old input() function (which evaluated the input as a Python expression) was removed.

Note:

In Python 3, use input() to read input as a string.
