asking a user for his or her name

and say hello so and so instead of just

and in Python it's actually pretty easy

all you have to do is just say let's

just say I want to store the user's name

in a variable called name and then I'll

sign it whatever the return value of
sign it whatever the return value of

this function input is and notice that

I'm still passing in this string hello

prompting them for their name and then

well now since I have name actually

stored somewhere I've set name equals or

your name I can actually reuse that
