Implement a Password Manager Class in Python
Python3 ExamplesWe will use Python to implement a simple password manager class. This class will allow users to store, retrieve, and delete passwords. The passwords will be stored in a dictionary, where the keys are account names and the values are passwords. For simplicity, the passwords will be stored in plain text, but in real-world applications, encryption should be used to protect passwords.
Example
class PasswordManager:
def __init__(self):
self.passwords = {}
def add_password(self, account, password):
self.passwords[account] = password
print(f"Password for {account} added successfully.")
def get_password(self, account):
if account in self.passwords:
return self.passwords[account]
else:
return f"No password found for {account}."
def delete_password(self, account):
if account in self.passwords:
del self.passwords[account]
print(f"Password for {account} deleted successfully.")
else:
print(f"No password found for {account}.")
def list_accounts(self):
if self.passwords:
print("Accounts with stored passwords:")
for account in self.passwords:
print(account)
else:
print("No accounts with stored passwords.")
def __init__(self):
self.passwords = {}
def add_password(self, account, password):
self.passwords[account] = password
print(f"Password for {account} added successfully.")
def get_password(self, account):
if account in self.passwords:
return self.passwords[account]
else:
return f"No password found for {account}."
def delete_password(self, account):
if account in self.passwords:
del self.passwords[account]
print(f"Password for {account} deleted successfully.")
else:
print(f"No password found for {account}.")
def list_accounts(self):
if self.passwords:
print("Accounts with stored passwords:")
for account in self.passwords:
print(account)
else:
print("No accounts with stored passwords.")
Code Analysis:
__init__The method initializes an empty dictionarypasswords, used to store accounts and passwords.add_passwordThe method accepts two parameters:accountandpassword, and adds them to thepasswordsdictionary.get_passwordThe method accepts one parameteraccount, and returns the password for that account. If the account does not exist, it returns a corresponding prompt message.delete_passwordThe method accepts one parameteraccount, and from thepasswordsdictionary, deletes the account and its password. If the account does not exist, it returns a corresponding prompt message.list_accountsThe method lists all accounts that have stored passwords. If no account has stored passwords, it returns a corresponding prompt message.
Output:
Example
# Example usage
pm = PasswordManager()
pm.add_password("email", "myemailpassword")
pm.add_password("bank", "mybankpassword")
print(pm.get_password("email")) # Output: myemailpassword
pm.delete_password("bank")
pm.list_accounts() # Output: Accounts with stored passwords: email
pm = PasswordManager()
pm.add_password("email", "myemailpassword")
pm.add_password("bank", "mybankpassword")
print(pm.get_password("email")) # Output: myemailpassword
pm.delete_password("bank")
pm.list_accounts() # Output: Accounts with stored passwords: email
This simple password manager class can help you manage passwords for multiple accounts, and it can be extended as needed, for example, by adding encryption functionality or persistent storage.
