在现有字典中添加一个新键：值，然后使用泡菜保存该键，然后在另一个python文件中加载该字典

因此，基本上，我试图创建一个密码管理器，可以保存我的电子邮件和密码。首先，我创建了一个字典，并使用泡菜：

import pickle

passDB = {} # this is the dictionary
key = input("Email: ") # taking email
password = input("Password: ") # taking password
passDB[key]= password # assigning new email and password into the dictionary
pickle.dump( passDB, open( "passDB.p", "wb" ) ) # saving it as passDB.p

将其保存为add2db.py。然后，我在Python文件中创建了一个密码管理器：

import pickle
passDB = pickle.load( open( "passDB.p", "rb"))
query1 = input("Search your email account to get password: ").lower()
if query1 in passDB.keys():
    print(passDB[query1])
else:
    print("Nothing such email in database")

将其保存为Passman.py。因此，这里的问题是，假设我在add2db.py文件中添加了一个新的电子邮件和密码。它添加了完美。当我尝试通过Passman.py文件中的电子邮件搜索密码时，它会完美显示密码。但是同样，当我尝试在Add2db.py中添加另一个电子邮件和密码时，它再次添加了成功，但删除了我首先添加的现有电子邮件和密码。当我尝试使用passman.py查找时，没有第一个电子邮件和密码的迹象谁能解决以下内容？

我想要一个创建add2db.py文件，该文件不断向现有词典添加新的电子邮件和密码。字典必须包含所有以前的电子邮件和密码。这样我就可以在passman.py中查找所有电子邮件和密码

So basically, I am trying to create a password manager where I can save my email and password.
first I created a dictionary and save it using pickle:

import pickle

passDB = {} # this is the dictionary
key = input("Email: ") # taking email
password = input("Password: ") # taking password
passDB[key]= password # assigning new email and password into the dictionary
pickle.dump( passDB, open( "passDB.p", "wb" ) ) # saving it as passDB.p

Saved it as add2db.py. Then I created a password manager in python file like this:

import pickle
passDB = pickle.load( open( "passDB.p", "rb"))
query1 = input("Search your email account to get password: ").lower()
if query1 in passDB.keys():
    print(passDB[query1])
else:
    print("Nothing such email in database")

Saved it as passman.py.
So, the problem here is, Suppose I added a new email and password into the add2db.py file. It adds perfectly. When I try to search password by email in passman.py file, it shows the password perfectly. But again, when I try to add another email and password in add2db.py, it again adds successfully but removes the existing email and password I added at first. And there is no sign of first email and password when I try to lookup using passman.py
Can anyone solve the following?

I want a create add2db.py file that keeps adding new email and password to an existing dictionary. The dictionary must contain all previous email and passwords. So that I can look for all the email and password in passman.py
