Python函数的类型提示功能

# 函数的类型提示功能 # python 是解释型，强类型，动态类型 # name:str age:int hobbies:tuple # # 无类型提示 # def register(name,age,hobbies): # print(name) # print(age) # print(hobbies) # return 1111

# 函数的类型提示功能，整体返回成int类型 # def register(name:str,age:int,hobbies:tuple)->int: # print(name) # print(age) # print(hobbies) # return 1111 # # res = register(1,'aaa',[1,]) # print(res) # # res = register('lsj',18,('play','music')) # print(res)

# 加入默认参数 # def register(name:str='lsj',age:int=18,hobbies:tuple=(1,2))->int: # print(name) # print(age) # print(hobbies) # return 1111 # # res = register('lsj',18,('play','music')) # print(res) # # print("=============================") # res = register() # 不传参 # print(res)

# :冒号后跟的是提示信息
def  register(name:'必须传入名字',age:111,hobbies:'必须传入元组')->'返回的是整型int': print(name) print(age) print(hobbies) return 1111 res = register('lsj',18,('play','music')) print(res) # 查看提示信息功能
print(register.__annotations__) # {'name': '必须传入名字', 'age': 111, 'hobbies': '必须传入元组', 'return': '返回的是整型int'}
