Python实现用户管理系统
用户管理系统：
实现功能：
- 增添删除用户
- 用户登录
- 显示用户信息
直接上代码：
def Init_Gui(): #初始界面（给提供用户选择）
print '*' * 35
str = """ Welcome To User Login System: *
1.Resgiter: *
2.Login: *
3.Del User: *
4.Show: *
5.Choice: *
6.Exit: *"""
print str
print '*' * 35
user_info = { #字典保存用户信息
"name": [],
"passwd": [],
"age": [],
"gender":[]
}
def create_user(): #增加用户函数
new_user = raw_input("Input Username:>>>")
if new_user in user_info["name"]: #判断用户是否存在
print "User Exists"
create_user()
else:
user_info["name"].append(new_user) #添加用户名到字典中的用户名列表
passwd = raw_input("Input passwd:>>>")
user_info["passwd"].append(passwd) #添加密码
# age = raw_input("Input age>>>")
# user_info["age"].append(age) #
gender_choice = (0,1,2)
while True:
gender = raw_input("Input gender(1:Male,0:Female,2:Else):>>>")
if not gender:
user_info["gender"].append("None")
break
elif gender.isdigit():
if int(gender) in gender_choice:
user_info["gender"].append(gender) #添加性别信息
break
else:
print "Incorrect Number:"
else:

break

break
else:

new_user = raw_input("Input Del_username:>>>")
if new_user in user_info["name"]: #若用户存在于列表
index = user_info["name"].index(new_user)
user_info["name"].remove(new_user)
del user_info["passwd"][index]
del user_info["age"][index]
del user_info["gender"][index] #删除所有用户信息
print "Successfuly deleted"
else:
print "The User doesn't exist" #否则输出用户不存在
def show_all(): #显示所有用户信息
if user_info["name"]: #判断列表是否为空
for index in range(len(user_info["name"])):
print "name:%s " % user_info["name"][index],
print "passwd:%s " % user_info["passwd"][index],
print "age:%s " % user_info["age"][index],

print "--------- User Login Interface-------"

if username in user_info["name"]: #判断时有存在用户
i = 0
while i <3: #用户有三次输入密码机会
passwd = raw_input("Input Passwd:>>>")
index = user_info["name"].index(username) ##用户在用户列表的索引作为密码列表的索引
user_passwd = user_info["passwd"][index]
if passwd == user_passwd: #若密码匹配
print "Sussfully Logged in" #输入成功则跳出循环
break
else:
print "Incorrect Passwd:(You have 3 chances)"
print "This is %dst time " % (i+1)
i+=1
else:
print "Incorrect Username,please try again."
Init_Gui()
def choice():
