Day1: Write A Job logon interface and draw the corresponding flowchart. day1 Flowchart

Job Requirements:

1. Enter the user name and password

2. The welcome information is displayed after the authentication is successful.

3. Lock after three wrong attempts

The Code is as follows:

_user_list =[]_user_dict = {}_login_error_count = 0while True:    user_naming = input('Plass input your name :')    user_password = input('Plass input your password:')    user_data = open('UserPassWord')    for _user_data in user_data:        user_datas = _user_data.strip()        user_list = user_datas.split(',')        users_name = user_list[0].strip()        users_password = user_list[1].strip()        users_lock = user_list[2].strip()        users_error = int(user_list[3].strip())        _user_dict[users_name] = {'name':users_name,'password':users_password,'lockcount':users_lock,'errorcount':users_error}    user_data.close()    if user_naming in _user_dict.keys():        if _user_dict[user_naming]['lockcount'] == '1' :            print('you have been locked')            break        if user_naming == _user_dict[user_naming]['name'] and user_password == _user_dict[user_naming]['password']:            print('welcome to enter the system ')            break        else:            _user_dict[user_naming]['errorcount'] += 1            if  _user_dict[user_naming]['errorcount']  <  3 :                print('the password was wrong,plase try again!')                write_data = open('UserPassWord','w+')                for user_value in _user_dict.values():                    _user_list = [user_value['name'],user_value['password'],str(user_value['lockcount']),str(user_value['errorcount'])]                    _users_list = ','.join(_user_list)                    write_data.write(_users_list+'\n')                write_data.close()            else:                print('your name have locked!')                write_data = open('UserPassWord','w+')                _user_dict[user_naming]['lockcount'] = 1                _user_dict[user_naming]['errorcount'] = 0                for user_value in _user_dict.values():                    _user_list = [user_value['name'],user_value['password'],str(user_value['lockcount']),str(user_value['errorcount'])]                    _users_list = ','.join(_user_list)                    write_data.write(_users_list+'\n')                write_data.close()    else:        print('your password was wrong!')        _login_error_count += 1        if _login_error_count > 2:            break
