invoking yield for a generator in another function

Question

suppose I have some manager object. This object\'s API has a main_hook function, that gets another function f as it\'s argument, and runs the given

Answer 1

I am not quite sure what exactly you are trying to achieve, so maybe if you can explain the problem more instead of giving solution that would be better.

From my partial understanding why don't you do something like this

def main_hook(self,f):
    while (self.shouldContinue()):
        #do some preparations
        stop_and_do_stuff = f(self)
        if stop_and_do_stuff :
            yield
            
        #do some tear down
    

So basically f returns a flag to stop or not, and if it says stop we yield to function which called main_hook and that function can continue after doing some stuff

e.g.

class A(object):
    def main_hook(self,f):
        while (self.shouldContinue()):
            #do some preparations
            stop = f(self)
            if stop:
                yield
                
            #do some tear down
        
    def shouldContinue(self):
        return True
    
def f(a):
    return True

a = A()
for x in a.main_hook(f):
    print x
