个人练习(一)
刚入门的一个小白,找本书看完了基础,自己根据条件写了一个简单的小练习:
这个接口主要实现1.在本目录下创建一个保存账户和密码的txt文件 2.支持用户自我创建账户和密码 3.能够查询到用户的数量 4.如果更改掉基于目录下创建的txt文件,可能会导致错误
算是我自学记录努力的一个过程,每天不断在学习中!有什么多余或者更好的建议往大神指点指点。。帮助下我这小白...
代码如下:
def Main():
#选择界面自动运行函数
is_choice = Prompt() #is_choice 是选择的0,1,2等等
while True:
if is_choice == ‘0‘:
is_choice = Prompt()
elif is_choice == ‘1‘:
is_choice = Create()
elif is_choice == ‘2‘:
Login()
is_choice = Prompt()
elif is_choice == ‘3‘:
show=Information()
print(‘该数据中存在‘+ str(len(show)) + ‘个用户:‘)
for s in show:
print(‘用户:‘+s)
is_choice = Prompt()
#显示界面
def Prompt():
print(‘请选择您的操作\n请输入数字代表选择:\n0.主界面 1.创建账户 2.登陆账户 3.查询账户‘)
is_num = input(‘请选择:‘)
return is_num
#创建账户
def Create():
is_name = input(‘请输入您要创建的账户:‘)
keep = True
keep = Judge(is_name)
while keep:
with open(‘user.txt‘,‘a‘) as fu:
fu.write(is_name+‘\n‘)
is_psword = input(‘请输入你创建的账户密码:‘)
with open(‘psword.txt‘,‘a‘) as fp:
fp.write(is_psword+‘\n‘)
break
is_numer = Prompt()
return is_numer
#判断该用户是否注册过
def Judge(name):
_file = ‘user.txt‘
lister = []
kip = True
try:
with open(_file,‘r‘) as ff:
lister=ff.read().splitlines()
except FileNotFoundError:
with open(_file, mode=‘w‘, encoding=‘utf-8‘) as ff:
pass
for val in lister:
if val == name:
print(‘不好意思,用户已存在,请重新创建‘)
kip = False
break
else:
kip = True
return kip
#查询账户信息
def Information():
user_name = []
try:
_file = ‘user.txt‘
with open(_file,‘r‘) as ff:
user_name=ff.read().splitlines()
except FileNotFoundError:
with open(_file, mode=‘w‘, encoding=‘utf-8‘) as ff:
pass
return user_name
#登陆账户
def Login():
name_up = input(‘请输入您的登录名:‘)
kap = is_Login(name_up)
if kap:
psword_up = input(‘请输入您的账户密码:‘)
pa_Word(name_up,psword_up)
#判断登录名是否存在账户中
def is_Login(name):
user_up = []
is_NaN = True
kap = False
try:
_file = ‘user.txt‘
with open(_file,‘r‘) as ff:
user_up=ff.read().splitlines()
except FileNotFoundError:
print(‘您输入的用户不存在,请核实后输入!‘)
if len(user_up):
for i in user_up:
if name == i:
kap = True
else:
#print(‘该用户不存在!‘)
continue
else:
print(‘该用户不存在!‘)
is_choice = Prompt()
return kap
#判断用户输入的密码
def pa_Word(name,word):
_user = ‘user.txt‘
_pass = ‘psword.txt‘
us_user = []
us_pass = []
with open(_user,‘r‘) as ff:
us_user=ff.read().splitlines()
with open(_pass,‘r‘) as ff:
us_pass=ff.read().splitlines()
user_index = us_user.index(name)
if us_pass[user_index] != word:
print(‘不好意思,你的密码输入错误,请重新选择!‘)
else:
print(‘恭喜您,登陆成功!亲爱的:‘+name)
Main()
