I'm still a beginner in python and my English is not really good, so I may have a little bit of understanding the explanation given in my course.

So I have this code:

class Apple:
    def __init__ (self,color,flavor):
        self.color=color
        self.flavor=flavor
        
    def __str__(self):
        return "This apple is {} and its flavor is {}".format(self.name,self.flavor)
        
jonagold=Apple("red","sweet")
print(jonagold)

The only purpose I see in using the __str__ method, I don't have to write the method in the print () line. If I changed the __str__ method with:

def say(self):
    return "This apple is {} and its flavor is {}".format(self.name,self.flavor)

I would just need to type

print(jonagold.say())

And I would get the same answer. What are the other purpose of using __str__? In what situation would I need to use the __str__?

Thank you :)
