Python2.x Python raw_input() Function
The python raw_input() function is used to get input from the console.
raw_input() treats all input as a string and returns a string type.
Note: Both the input() and raw_input() functions can receive strings, but raw_input() reads the console input directly (it can receive any type of input). For input(), it expects to read a valid Python expression, meaning you must enclose strings in quotes when entering them, otherwise it will raise a SyntaxError.
Unless you have a specific need for input(), it is generally recommended to use raw_input() for user interaction.
Note: In python3, input() receives a str type by default.
Function Syntax
raw_input()
Parameter Description:
- prompt: Optional. A string that can serve as a prompt.
Examples
raw_input() treats all input as a string
>>>a = raw_input("input:")
input:123
>>>type(a)
<type 'str'> # String
>>>a = raw_input("input:")
input:tutorial
>>>type(a)
<type 'str'> # String
>>>input() requires a Python expression
>>>a = input("input:")
input:123 # Enter an integer
>>>type(a)
<type 'int'> # Integer
>>>a = input("input:")
input:"tutorial" # Correct, string expression
>>>type(a)
<type 'str'> # String
>>>a = input("input:")
input:tutorial # Error, not an expression
