python之常用的数据处理方法

１．生成６位数验证码

"".join([random.choice(chars) for i in range(６)])

２．密码加密

import hashlib

def encryptPwd(pwd, salt):

    h1 = hashlib.md5()

    dst = pwd + salt

    h1.update(dst.encode("utf8"))

    pwdEncode = h1.hexdigest()

    return pwdEncode.upper()

oldPwd=''

newPwd=encryptPwd('', '加盐')

print(newPwd)

#7843D1005A1BE1C6606D555E7993E249

３．姓名首字母排序

from pypinyin import lazy_pinyin

def pYinNameMap(names):

    pyin_name_tuples = [(''.join(lazy_pinyin(n)), n) for n in names]

    pyinName = {}

    ss = sorted(pyin_name_tuples, key=lambda x:x[0])

    for item in ss:

        firChar = item[0][0]

        name = item[1]

        if firChar not in pyinName.keys():

            pyinName[firChar] = [name]

        else:

            pyinName[firChar].append(name)

    return pyinName

pyinName=pYinNameMap(['张三','李四'])

print(pyinName)

#{'l': ['李四'], 'z': ['张三']}

４．时间转为字符串类型的日期"2018年10月18日"

import datetime

i=datetime.datetime.now().date()

print('%s年%s月%s日'%(i.year,i.month,i.day))

#2018年10月18日

5.字符串日期取年月日

def dateToymd(date):

    (y, m, d) = map(int, date.split('-'))

    return (y, m, d)

print(dateToymd("2018-1-3"))

#(2018, 1, 3)

６．字符串日期返回一星期的第几天

date.weekday（）返回的0-6代表周一--到周日

import datetime

def dateToymd(date):

    (y, m, d) = map(int, date.split('-'))

    return (y, m, d)

def WeekToDay(date):

    ymd = dateToymd(date)

    print(ymd)

    return datetime.date(*ymd).weekday()

print(WeekToDay("2018-10-18"))

#(2018, 10, 18)

#

datetime.datetime.isoweekday（）返回的1-7代表周一--周日；

import datetime

def dateToymd(date):

    (y, m, d) = map(int, date.split('-'))

    return (y, m, d)

def WeekToisoday(date):

    ymd = dateToymd(date)

    print(ymd)

    return datetime.date(*ymd).isoweekday()

print(WeekToisoday("2018-10-18"))

#(2018, 10, 18)

#

７．返回两个字符串日期之前的所有日期，并且以列表的形式，eg: '2018-09-02', '2018-09-04' 返回　['2018-09-02', '2018-09-03', '2018-09-04']

8.一天的一段时间之后

from datetime import datetime

str='2018-12-11'

timeNow=datetime.strptime(str,'%Y-%m-%d')

print(timeNow)

EndDate = timeNow.replace(hour=23, minute=59, second=59, microsecond=59)

print(EndDate)

#2018-12-11 00:00:00

#2018-12-11 23:59:59.000059

未完待续．．．．．．
