python調用時間裝飾器檢測函數運行時間

用一個裝飾器，監控程序的運行時間

import time

def count_time(func):
    def int_time(*args, **kwargs):
        start_time = time.time()  # 程序開始時間
        func()
        over_time = time.time()   # 程序結束時間
        total_time = over_time - start_time
        print('程序共計%s秒' % total_time)

    return int_time

@count_time
def main():
    print('>>>>開始計算函數運行時間')
    x = 0
    for i in range(1000000):
        x=x//13
    print(x)

if __name__ == '__main__':
    main()
