python基础：datetime模块-毫秒时间差-微秒时间差

1 datetime

import datetime
access_start = datetime.datetime.now()
access_start_str = access_start.strftime('%Y-%m-%d %H:%M:%S')

access_end = datetime.datetime.now()
access_end_str = access_end.strftime('%Y-%m-%d %H:%M:%S')
access_delta = (access_end-access_start).seconds*1000

import os
import time
hello = '%s-%s' % (time.strftime('%Y%m%d-%H%M%S'), os.urandom(2).encode('hex'))
print(hello)
# 20180522-144343-d6f1

hello = '%s%s' % (time.strftime('%Y%m%d%H%M%S'), os.urandom(2).encode('hex'))
print(hello)
# 20180522144436c412

 

2 简单封装以及获取毫秒级别时间差和微秒级别时间差

from __future__ import division
import datetime
import time



def t():
    t1 = datetime.datetime.now()
    ts1 = t1.strftime('%Y-%m-%d %H:%M:%S')
    return t1,ts1


def millis(t1, t2):
    micros = (t2 - t1).microseconds
    print("micros: ",micros)
    delta = micros/1000
    return delta


def micros(t1, t2):
    delta = (t2-t1).microseconds
    return delta


def access_log(route_rule, headers, t1, t2, delta, db_delta, api_delta):

    access = {}
    access['route'] = route_rule
    access['headers'] = headers
    access['route_start'] = t1
    access['route_end'] = t2
    access['route_delta'] = delta
    access['db_delta'] = db_delta
    access['api_delta'] = api_delta
    return access
