实例02  模拟幼儿园分苹果（除数不能为0）

def division():
"'功能：分苹果'"

实例03  模拟幼儿园分苹果（每个人至少分到一个苹果）

def division():
"'功能：分苹果'"
print("\n=======================分苹果了=======================\n")
apple = int(input("请输入苹果的个数："))
children = int(input("请输入来了几个小朋友："))

print("\n出错了 ~_~—",e)

 

 

 

 

 实例04  模拟幼儿园分苹果（应用断言调试）

division()
except AssertionError as e:
print("\n输入有误：",e)
