python:使用迭代方法生产随机码
使用迭代方法取随机码，而不是全部返回，保存函数，为以后开发系统使用。1

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from random import choice
codeOrig = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890"
def makePromoteCode(codeLength=4):
Code = ''
for i in range(0,codeLength):
Code += choice(codeOrig)
return Code
def ReturCode(codeLength=4,codeCount=10):
for i in range(0,codeCount):
Code = makePromoteCode(codeLength=codeLength)
yield Code
#print (Code)
s = ReturCode(8,4)
print (s.__next__())
print (s.__next__())
print (s.__next__())
print (s.__next__())
如果是需要一次性返回随机码方法为：

import random
codeOrig = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890"
def makePromoteCode(codeLength=12,codeCount=200):
for i in range(codeCount):
promotecode = ""
for x in range(codeLength):
promotecode += random.choice(codeOrig)
print (promotecode)
#a = 'abcdefghijklmnopqrstuvwxyz'
if __name__ == '__main__':
makePromoteCode(34,10)
