python 脚本生成随机 字母 + 数字密码功能

#coding:utf-8
import random,string
def GetPassword(length):
  # 随机生成数字个数
  Ofnum=random.randint(1,length)
  Ofletter=length-Ofnum
  # 选中ofnum个数字
  slcNum=[random.choice(string.digits) for i in range(Ofnum)]
  # 选中ofletter个字母
  slcLetter=[random.choice(string.ascii_letters) for i in range(Ofletter)]
  # 打乱组合
  slcChar=slcLetter+slcNum
  random.shuffle(slcChar)
  # 生成随机密码
  getPwd=''.join([i for i in slcChar])
  return getPwd
if __name__=='__main__':
  print( GetPassword(6)) #GetPassword()自定义随机密码长度
