需要使用的库：pymssql(用于连接SQL Server), PyQt5(用于窗口的制作)
首先编写DOS界面的密码生成器，以及将程序与数据库相连接，用于存储和查询
PasswordDOS.py
1 from random import randint
2 import pymssql
3
4
5 def connect_to_sql():
6 print(‘连接中...‘)
7 connect = pymssql.connect(‘(local)‘, ‘sa‘, ‘123456789‘, ‘Password‘)
8 if connect:
9 print(‘连接成功...‘)
10 else:
11 print(‘未连接‘)
12 exit()
13 return connect
14
15
16 def rand_password():
17 whole_char = r‘[email protected]#$%^&*‘
18 char_number = len(whole_char)
19 password_length = input(‘please input password lenght: ‘)
20 password = []
21 for _ in range(0, int(password_length)):
22 password.append(whole_char[randint(0, char_number - 1)])
23 return password
24
25
26 def inquiry_password(cursor):
27 name = input(‘please input password for use: ‘)
28 if name == ‘‘:
29 sql = r"select * from password"
30 else:
31 sql = r"select * from password where id =‘" + name + "‘"
32 cursor.execute(sql)
33 result = cursor.fetchall()
34 if len(result) == 0:
35 print(‘不存在该密码‘)
36 else:
37 for value in result:
38 print(value[0]+‘的密码是：‘+value[1])
39
40
41 def add_password(connect, cursor):
42 name = input(‘please input password for use: ‘)
43 pwd = input(‘please input password: ‘)
44 if pwd == ‘‘:
45 pwd = ‘‘.join(rand_password())
46 sql = r"insert into password values(‘" + name + "‘, ‘" + pwd + "‘)"
47 cursor.execute(sql)
48 connect.commit()
49 print(name + ‘的密码是：‘ + pwd)
50
51
52 def delete_password(connect, cursor):
53 name = input(‘please input password for use: ‘)
54 sql = r"delete from password where id=‘" + name + "‘"
55 cursor.execute(sql)
56 connect.commit()
57
58
59 def change_password(connect, cursor):
60 name = input(‘please input password for use: ‘)
61 pwd = input(‘please input password: ‘)
62 if pwd == ‘‘:
63 pwd = ‘‘.join(rand_password())
64 sql = r"update password set pwd=‘" + pwd + "‘where id=‘" + name + "‘"
65 cursor.execute(sql)
66 connect.commit()
67 print(name + ‘的密码是：‘ + pwd)
68
69
70 def run():
71 connect = connect_to_sql()
72 cursor = connect.cursor()
73 while True:
74 flag = input(‘please input (A/D/C/I/E{add,delete,change,inquiry,exit}): ‘)
75 if flag == ‘A‘ or flag == ‘a‘:
76 add_password(connect, cursor)
77 elif flag == ‘D‘ or flag == ‘d‘:
78 delete_password(connect, cursor)
79 elif flag == ‘C‘ or flag == ‘c‘:
80 change_password(connect, cursor)
81 elif flag == ‘I‘ or flag == ‘i‘:
82 inquiry_password(cursor)
83 elif flag == ‘E‘ or flag == ‘e‘:
84 break
85 connect.close()
86
87
88 if __name__ == ‘__main__‘:
89 run()
将DOS界面的程序进行稍微修改，用于窗口界面的导入文件
password.py
1 from random import randint
2 import pymssql
3
4
5 def connect_to_sql():
6 print(‘连接中...‘)
7 connect = pymssql.connect(‘(local)‘, ‘sa‘, ‘123456789‘, ‘Password‘)

10 else:
11 print(‘未连接‘)
12 exit()
13 return connect
14
15
16 def rand_password(password_length):
17 whole_char = r‘[email protected]#$%^&*‘
18 char_number = len(whole_char)
19 # password_length = input(‘please input password lenght: ‘)
20 password = []
21 for _ in range(0, int(password_length)):
22 password.append(whole_char[randint(0, char_number - 1)])
23 return password
24
25
26 def inquiry_password(cursor, name):
27 # name = input(‘please input password for use: ‘)
28 if name == ‘all‘ or name == ‘ALL‘:

31 return ‘请输入账号‘
32 else:

34 cursor.execute(sql)
35 result = cursor.fetchall()
36 if len(result) == 0:
37 # print(‘不存在该密码‘)
38 return ‘不存在该密码‘
39 else:
40 _: str = ‘‘
41 for value in result:
42 # print(value[0]+‘的密码是：‘+value[1])
43 _ += value[0]+‘的密码是：‘+value[1]+‘\n‘
44 return _
45
46
47 def add_password(connect, cursor, name, pwd, length=16):
48 # name = input(‘please input password for use: ‘)
49 # pwd = input(‘please input password: ‘)
50 if pwd == ‘‘:
51 pwd = ‘‘.join(rand_password(length))
52 sql = r"select id from password where id = ‘" + name + "‘"
53 cursor.execute(sql)
54 PasswordId = cursor.fetchone()
55 if PasswordId == (name, ):
56 return ‘密码已存在，请使用修改‘
57 sql = r"insert into password values(‘" + name + "‘, ‘" + pwd + "‘)"
58 cursor.execute(sql)
59 connect.commit()
60 # print(name + ‘的密码是：‘ + pwd)
61 result = name + ‘的密码是：‘ + pwd
62 return result

64
65 def delete_password(connect, cursor, name):
66 # name = input(‘please input password for use: ‘)
67 if name == ‘‘:
68 return ‘请输入账号‘
69 sql = r"select id from password where id = ‘" + name + "‘"
70 cursor.execute(sql)
71 PasswordId = cursor.fetchone()
72 if PasswordId is None:
73 return ‘不存在‘ + name + ‘账号‘
74 sql = r"delete from password where id=‘" + name + "‘"

108 break

112 if __name__ == ‘__main__‘:
113 run()
使用PyQt5库编写窗口程序
IPassword.py

暂时可以实现密码的生成、存储、修改、查询、删除的功能。
