What's the Key Difference Between Python 2's `raw_input()` and Python 3's `input()`?

What's the Difference Between raw_input() and input() in Python 3?

In Python 2, the raw_input() function was used to gather user input. It was designed to accept raw text without any processing or conversion. In Python 3, however, raw_input() has been replaced by input().

Key Distinction

The fundamental difference between raw_input() and input() lies in their behavior:

  • raw_input() (Python 2): Gathers raw text without performing any type conversion.
  • input() (Python 3): Accepts input and automatically converts it to a Python object, considering its type (e.g., integer, float, string).

Rename and Deprecation

In Python 3, raw_input() was renamed to input(). The old input() function is no longer supported. To simulate the functionality of the old input() (which prompted for user input but returned raw text), you can use the following syntax:

input_string = eval(input())

Note: Using eval() to parse input is generally discouraged due to security risks. It's safer to employ other methods for data validation and conversion.
