我是Python新手，但我有其他OOP语言的经验.我的课程没有解释python中的主要方法.
请告诉我main方法在python中是如何工作的？我很困惑，因为我试图将它与Java进行比较.
def main():
# display some lines
if __name__ == "__main__": main()
main是如何执行的，为什么我需要这个奇怪的if来执行main.当我删除if时，我的代码将被终止而没有输出.
最小码-
class AnimalActions:
def quack(self): return self.strings['quack']
def bark(self): return self.strings['bark']
class Duck(AnimalActions):
strings = dict(
quack = "Quaaaaak!",
bark = "The duck cannot bark.",
)
class Dog(AnimalActions):
strings = dict(
quack = "The dog cannot quack.",
bark = "Arf!",
)
def in_the_doghouse(dog):
print(dog.bark())
def in_the_forest(duck):
print(duck.quack())
def main():
donald = Duck()
fido = Dog()
print("- In the forest:")
for o in ( donald, fido ):
in_the_forest(o)
print("- In the doghouse:")
for o in ( donald, fido ):
in_the_doghouse(o)
if __name__ == "__main__": main()
