It's not about Pyhton.

But nevertheless, to answer you straightly. Lets say you have a function:

def doSomethingWithParmas(params):
    params.doSomething()

Now you can call it later on with:

print doSomethingWithParams(myParams)

or/and

print doSomethingWithParams(yourParams)

It's how functions work, you can call it with whatever params you like, all that function cares, is that they are some kind of params that it can handle.

EDIT: A remark: I have never coded a line of Python in my life.
