 A Problem With The Body of My Function
#1
Hello,

I'm writing here with only a slight degree of knowledge, but I think, I hope, this is the right place to ask the right questions.

Okay, I have set up code where I have to do the following:

perform a calculation underneath my header,

def volume(cargo):


THE BODY IS HERE.




Further down, I have the following assert commands

test_volume():

assert volume(cargo) = a number
assert volume(cargo) = a number

test_volume()

the number (a number) to the right of the assert command can't be greater than the total_net_load of the truck when it is MULTIPLIED BY THE CARGO, and … well … I HAVE THAT NUMBER for the total_net_load, and I have the number for the cargo in the expression after the assert commands (a number is written in), but how in the hell do I transfer this up to the function - WHICH I MUST USE THE RETURN FUCNTION FOR - so this is stored in the shell-memory?


I have thought up the following ''code''; but of course it fails.

def volume(cargo)
'''Statement here'''
total_net_load = x
cargo / total_net_load = a number
return <= a number

okay, I'm going to try this one out I have just wrote, but if it doesn't work i'm posting this question - thanks. didn't work: please, someone with a higher IQ than me, please point me in the right direction.


Also, I must add, i'm not looking for the answer, just a an explination of what where my thinking is wrong, thanks.

Please, use proper tags when post code, traceback, output, etc.
See BBcode help for more info.

Working from your code, the def volume(cargo) statement needs a colon at the end.
Can't tell if your indentation is correct, please repost using proper tags. Indentation is critical.
total_net_load = x Where does the interpreter get the value for x?
Next line - It appears you do not understand assignment statements. The = means it is an assignment. They are in the format
<variable> = <expression>, not the other way around.
No idea what you are trying to do with the return statement. That needs to be in the format return <expression> where <expression> resolves to a variable.

Note that in Python variables are objects, so you can substitute the word object in any of the above.
