You can search the Internet for various documentations and tutorials on Python.
One of them is on W3School that describes how to handle user input in Python:
For Example if you want the user to enter his/age you can prompt the user by using this line of code :
age = int(input("Enter your age : "))
for accepting the name and other details :
name = input('Enter your name : ')
To ask a simple question like what school you go to, do this:
school = input("What school do you go to? : ")
print("You go to " , school)
If you want to ask a different question, just replace the variable with what the question is about, replace the school question with yours then, print you start of the answer.
In Python 2.7 = username = raw_input("Enter username:") - This method is for Python2 which is approaching EOL.
In Python3 = username = raw_input("Enter username:")
Interestingly, Python will read the response as a string, so if you want to read a number and treat it as a number, I would recommend age = int(input("Enter your age : "))
