Why is the strength value unreachable?

Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

def SC():
    if Clevel_5 == True:
        strength = 5
    elif Clevel_4 == True:
        strength = 4
    elif Clevel_3 == True:
        strength = 3
    elif Clevel_2 == True:
        strength = 2
    elif Clevel_1 == True:
        strength = 1
#

the strength value is seen as unreachable.

Maybe show the larger code, and what "shows it as unreachable".

Basicly, strength is a local variable. It will not be visible outside the function.

Any variable you assign to in a function is local by default.

THATS HTE WHOLE CODE SIR

#

IT TELLS ME THAT ITS NOT REACHABLE IF I PUT IT IN THE FUNCTION

#

Python functions make any variable you assign to local by default:

x = 1
print(x) # prints 1

def f():
    x = 2 # local, _unrelated_ to the outer x
    print(x) # prints 2

f()
print(x) # prints 1

i didnt even ask for that

#

i know

if all your function does is assign a value to the local strength variable, what is its point?

tall temple
#

That's not "unreachable", it's saying you're setting strength and then never using it.

WERENT YOU THE GUY THAT TOLD ME TO USE FUNCTIONS A SECOND AGO

#

I AM SO CONFUSED

#

For how your code is presently structured you will need to use the global statement. Once you figure out why strength is unused.

#

Even outside a function, PyLance would complain the same way about this:

x = 1

because i never do anything with x.

tulip orchid
#

how do i use the global statement exactly?

tall temple
#

Inside the function, put:

    global strength

That say you're be ing the strength varoable from the main code, that it isn't a local variable.

#

Any of the main code variables you need to change will need marking as global:

    global strength, Clevel_2, ........

assuming any of these get changed.

If you're not assigning to them, you don't need this.
