用于对熊猫进行比较的循环

class Panda:
    def __init__(self, name, age, gender):
        self.name = name
        self.age = age
        self.gender = gender

# 创建熊猫对象列表
pandas = [
    Panda("Panda1", 5, "Male"),
    Panda("Panda2", 3, "Female"),
    Panda("Panda3", 4, "Male")
]

# 使用循环比较熊猫对象的年龄
for i in range(len(pandas)):
    for j in range(i+1, len(pandas)):
        if pandas[i].age == pandas[j].age:
            print(f"{pandas[i].name} and {pandas[j].name} have the same age.")
        elif pandas[i].age > pandas[j].age:
            print(f"{pandas[i].name} is older than {pandas[j].name}.")
        else:
            print(f"{pandas[i].name} is younger than {pandas[j].name}.")
