Python函数式编程

定义：对别的函数进行封装，运算，操作的函数

参数：

支持传别的函数名

任意参数  *args  **kwargs 

#coding:gbk

def test(m,n):
    return m+n

def func(func_name,*args,**kwargs):
    ret = func_name(*args,**kwargs)
    return ret+1

print(func(test,8,9))

超时处理函数

#coding:gbk
import time
import os

FILE_PATH = r'C:UsersMartinDesktopfinish'

def check_file_exist(file_name):
    return os.path.exists(file_name)


def handle_timeout(func_name, timeout, *args, **kwargs):
    interval = 1
    
    ret = None
    while timeout > 0:
        begin_time = time.time()
        ret = func_name(*args, **kwargs)
        if ret:
            break
        time.sleep(interval)
        timeout -= time.time() - begin_time
    
    return ret

ret = handle_timeout(check_file_exist,15,FILE_PATH)
print(ret)

import time

FILE_PATH = r'C:UsersMartinDesktopfinish'

def install():
    time.sleep(20)
    f = open(FILE_PATH,'w')
    f.close()
    
install()
