What you did, you failed to call the function that is why you facing this problem.
Use this instead and you can able to get the address of a function.
In Python v2.x
#!/usr/bin/python
def get_address():
address = raw_input("What is your address: ")
return address
a = get_address()
print a
What is raw_input?
It ask the user (the optional arg of raw_input([arg])), gets input from the user and returns the data input by the user in a string.
In Python v3.x:
#!/usr/bin/python
name=input('Enter your name : ')
print ("Welcome %s, Let us be friends!" % name);
