python：将时间戳格式化为yyyyMMdd hh:mm:ss

import time

#将10位时间戳或者13位转换为时间字符串，默认为2017-10-01 13:37:04格式
def timestamp_to_date(time_stamp, format_string="%Y-%m-%d %H:%M:%S"):
    time_array = time.localtime(time_stamp/1000)
    other_style_time = time.strftime(format_string, time_array)
    print other_style_time
    return other_style_time
timestamp_to_date(1593693029909)
