These functions are :
1. raw_input
2. input
The raw_input Function:
***********************
The raw_input([prompt]) function reads one line from standard input
and returns it as a string (removing the trailing newline).
#!/usr/bin/python
str = input("Enter your input: ");
print "Received input is : ", str
This prompts you to enter any string and it would display same string on the screen.
When I typed "Hello Python!", its output is like this −
Enter your input: Hello Python
Received input is : Hello Python
---------------------------------------------------------
The input Function:
*******************
The input([prompt]) function is equivalent to raw_input, except that it assumes the input is a valid Python expression and returns the evaluated result to you.
