1. Did you start your function definition with def ?
2. Does your function name have only characters and _ (underscore) characters?
3. Did you put an open parenthesis ( right after the function name?
4. Did you put your arguments after the parenthesis ( separated by
   commas?
5. Did you make each argument unique (meaning no duplicated names)?
6. Did you put a close parenthesis and a colon ): after the
   arguments?
7. Did you indent all lines of code you want in the function four
   spaces? No more, no less.
8. Did you ”end” your function by going back to writing with no indent
   (dedenting we call it)?

   When you run (”use” or ”call”) a function, check these things:

1. Did you call/use/run this function by typing its name?
2. Did you put the ( character after the name to run it?
3. Did you put the values you want into the parenthesis separated
   by commas?
4. Did you end the function call with a ) character?

Use these two checklists on the remaining lessons until you do not need
hem anymore.

Finally, repeat this a few times to yourself:
”To ’ run , ’ ’ c a l l , ’ or ’ use ’ a function a l l mean the same
thing . ”
