raw_input was used in Python 2 version but for latest Python 3 and higher versions input does the job of raw_input.
Also in raw_input argument is passed in the form of string. raw_input will give a name error in Python 3
raw_input does not covert input and take it as it is provided by the user.
Example of input() in Python 3
Your_name = input("What is your name? ")
print ("Hi, %s." % Your_name)
What is your name? Tia
