python怎么在Linux实现创建用户？
题主你好,
我以创建user1-user10个用户为例, 代码为测试截图如下:
1. 系统中不存在user1-user10:
执行脚本:
可以看到脚本执行后, 显示成功添加用户数10个, 失败0个.并且/etc/shadow中相应的用户信息也有了.
-------------
我们删掉user0, user1和user2:
可以看到/etc/shadow中的信息已经没有了user0-user2的信息了,此时我们再执行上面的脚本:
可以看到输出显示, 成功创建3个,就是我们之前删掉的那三个. 还有7个创建失败的, 因为用户本身就存在所以创建失败了.
希望可以帮到题主, 欢迎追问.
python设计函数,实现会员注册,要求用户名长度不小于3,密码长度不小于6, 注册时两次输入密码必须相同
def log_in():
username=input("输入用户名(不小于3位)")
if len(username)=3:
password=input("密码(不小于六位)")
if len(password)=6:
pass_1=input("再次输入密码")
if password==pass_1:
print("注册成功")
else:
print("两次输入密码不一致")
log_in()
else:
print("密码长度不符合要求")
log_in()
else:
print("帐号长度不符合要求")
log_in()
log_in()
python注册程序编写？
import
re
username_pattern
=
re.compile(r'_.{2,29}')
password_pattern
=
re.compile(r'(?=.*_)(?=.*d)(?=.*[A-Za-z]).{6,18}')
然后用相应的pattern，去match用户输入的字符串即可。
python批量注册账号 数据库会崩溃吗
不会的，一般不会同时运行太多账号，数据库可支撑力是很大的，不用担心这个问题，要批量注册所需要用的代码如下：
# -*- coding:utf-8 -*-
import random,urllib,urllib2
import re,time
x=input("请输入需要注册的数量:")
# x=raw_input() #转换成字符串的
def h(i,y):
user=str(random.randrange(10000000,99999999))
QQ=str(random.randrange(10001,999999999999))
pwd=str(random.randrange(100000,99999999))
url=""
data={"username":user,
"password":pwd,
"repassword":pwd,
"email":QQ+"@qq.com",
"qq":QQ,
"sex":"0",
"action":"newuser",
"submit":""}
data=urllib.urlencode(data)
req=urllib2.Request(url,data=data)
print data
# html=urllib2.urlopen(req).read()
# print(html)
html=urllib2.urlopen(req).read().decode('gbk')
# print(type(html))
reg=u'您已成功注册成为本站用户'
reg=re.compile(reg)
r=re.findall(reg,html)
if r!=[]:
print("注册成功，账号为%s，密码为%s，目前注册到第%s,还剩%s个"%(user,pwd,i+1,y-i-1))
f=open("c:user.txt","a")
f.write("%s----%s----%s@qq.com----%sn" %(user,pwd,QQ,QQ))
# f.write("qq----123456")
f.close()
for i in range(x):
h(i,x)
# 延时
time.sleep(2)
python怎么爬取简书用户名
初步的思路
今天在用Scrapy写代码的时候，对网页的结构也有了大致的分析，再加上之前罗罗攀的思路，初步我是通过专题入口
热门专题
image.png
image.png
专题管理员 （一般粉丝、文章、字数、收获喜欢、这几项数据都非常漂亮）
image.png
image.png
以上红框里的数据项就是我需要爬取的字段
但是以上的思路存在一点的问题：
存在一些简书用户并不是一些热门专题的管理员，但是其人气粉丝量也很高，这个思路可能无法将这些用户爬取下来
进阶的思路
热门专题
专题关注的人
专题关注的人的动态
推荐作者 粉丝信息

优点：
数据大而全，基本包含了99%的用户（个人猜测，不严谨）
缺点：
因为许多用户不止关注一个专题，而且其中包含了大量的新注册用户（数据很多为空），并且也有大量重复数据需要去重
