Exercises of Python Decorator

Directory 1. Please implement a decorator, the return value of the function +100 and then return 2. Please implement a decorator, through a call to make the function repeated 5 times 3. Please implement a decorator every time the function is called, the name of the function and the time point of calling the function are written into the file

1. Please implement a decorator, and return the value of the function +100 and then return

def wapper(func):

    def innner(*args,**kwargs):

        ret=func(*args,**kwargs)

        ret=print(ret+100)

        return ret

    return innner

@wapper

def func(number):

    return int(number)

func(100)

### Results: 200

2. Please implement a decorator and repeat the function 5 times through 1 call

def wapper(func):

    def innner(*args,**kwargs):

        count=0

        while count<5:

            func(*args,**kwargs)

            count+=1

    return innner

@wapper

def func():

    print(" Execute ")

func()

3. Please implement a decorator. When calling a function, write the name of the function and the time point of calling the function into the file

import time

def wapper(func):

    def inner(*args,**kwargs):

        with open("log",encoding="utf-8",mode="a+") as f:

            structime=time.localtime()

            f.write(f' Beijing Time: {time.strftime("%Y-%m-%d %H:%M:%S",structime)}  The name of the function is: {func.__name__}\n')

        ret=func(*args,**kwargs)

        return ret

    return inner

@wapper

def func():

    print(" Execute ")

func()

At the end, I recommend a very good learning tutorial for you, hoping to help you learn Python!
