# Function Checklist (ex19) |
||||
|
|
||||
ex19. |
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 parentheses separated by commas? |
||||
|
4. Did you end the function call with a ) character? |
||||
