Hey guys I'm having some trouble with a loop in python I`m working on. I simplified the code for this question since the core of the problem stays the same and it makes it easier to understand: So lets say I create two classes, one for Apples and one for Bananas. Their attributes are basically the same (name, color and price).
I wanted to define a method for the banana class which iterates over a list of apples and check first whether the price of the banana is the same as for one of the apple objects. If that is the case, the banana should take over that apple's name (again, it doesnt make any sense in this code, but its relevant for the actual project I'm working on). In the second place, the method is supposed to check whether the banana has the same color as one of the apple objects and then take over that apples name (I used an elif statement for that one).
Now, whenever I try to run that code with the 3 Banana objects, Banana1 and 3 are assigned to the correct Apple,but Banana2 is assigned to Apple1 even though it should be assigned to Apple 2. I experimented a bit and found out that when I remove the break statement at the end of my elif condition which checks for the matching color all Bananas are assigned to the correct Apple. However, since I would like to set up another elif condition I cannot delete that break statement, right?
If anyone could help me to understand what is wrong with my code I would be very grateful. Sorry if there is an obvious solution for this problem, I'm very new to python programming. Thanks in advance for your help! Heres the full code:
