I've got a code with different functions. Inside one of them there is a condition. I have to check if this condition occur to execute another function.

What's the proper way to do that? I've tried something like this but it doesn't work

Example:

class MyClass:

    def thisFunction(self):

        try: 

            "I'm doing things"

        except:

            self.stop = print("That's already done!")

    def thisOtherFunction(self):

        "I'm doing things with things done in thisFunction"

s = MyClass()

s.thisFunction()

if self.stop == None:

    s.thisOtherFunction()

else:

    pass

Thanks a lot!

Update

Actually it's a lot simplier doing:

class MyClass:

    def thisFunction(self):

        try: 

            "I'm doing things"

        except:

            self.stop = print("That's already done!")

   def thisOtherFunction(self):

        try:

            "I'm doing things with things done in thisFunction"

        except:

            pass

s = myClass()

s.thisFunction()

s.thisOtherFunction()

Thanks to Adam Smiths's example, I simply didn't think about that. Maybe it's not so much elegant, though.

Update2
Another way is to use def __init__ in this way:

    class MyClass:

        def __init__(self):

             self.commandStop = False

        def thisFunction(self):

            try: 

                "I'm doing things"

            except:

                self.commandStop = True

        def thisOtherFunction(self):

            "I'm doing things with things done in thisFunction"

        def conditionToGo(self):

             if self.commandStop == False:

                 print("That's already done!")

             else:

                 s.thisOtherFunction()

s = myClass()

s.thisFunction()

s.conditionToGo()

I've made patterns before where I had to do a series of transforms to a value and it needs to pass a test each time. You could construct that with:

def pipeline(predicate, transformers):

    def wrapped(value):

        for transformer in transformers:

            value = transformer(value)

            if not predicate(value):

                raise ValueError(f"{value} no longer satisfies the specified predicate.") 

        return value

    return wrapped

Then, to construct an example, let's say I need to do some math on a number but ensure that the number never goes negative.

operations = [

    lambda x: x+3,

    lambda x: x-10,

    lambda x: x+1000,

    lambda x: x//2

]



job = pipeline(lambda x: x>0, operations)

job(3)  # fails because the sequence goes 3 -> 6 -> (-4) -> ...

job(8)  # is 500 because 8 -> 11 -> 1 -> 1001 -> 500
