代碼如下

import time

def str_data_to_num(str_data):
    # 格式時(shí)間成毫秒
    strptime = time.strptime(str_data,"%Y-%m-%d %H:%M:%S")
    print("strptime",strptime)
    mktime = int(time.mktime(strptime)*1000)
    print("mktime",mktime)
    return mktime

def num_to_str_data(str_data):
    str_data = str_data/1000
    # 格式毫秒成指定格式時(shí)間
    str_data = time.localtime(str_data)  # 生成一個(gè)元祖式的時(shí)間
    print(str_data)
    strptime = time.strftime("%Y-%m-%d %H:%M:%S",str_data) #格式化元祖
    print("strptime",strptime)


if __name__ == '__main__':
    # 轉(zhuǎn)換一:格式化時(shí)間轉(zhuǎn)為毫秒
    str_data = "2018-06-21 23:59:59"
    str_data_to_num(str_data)

    # 轉(zhuǎn)換二:毫秒轉(zhuǎn)換為格式化時(shí)間
    str_data = 1529596799000  # 將整數(shù)的秒轉(zhuǎn)換為指定的時(shí)間格式
    num_to_str_data(str_data)
