Question

Exercise 3. Password locker. 1. You probably have accounts on many different websites. It’s a bad habit to use the same password for each of them because if any of those sites has a security breach, the hackers will learn the password to all of your other accounts. Develop a simple password manager software on your computer where you write the account name (blog, facebook, instagram, etc) as an argument and the password is copied to the clipboard. Then you can paste it into the website’s Password field. For example, if you execute this command line in your terminal: python3 ./pw.py instagram The password for Instagram (example: htS:D`t*hQH3]9"C) should be copied to the clipboard.

2. Add a second argument where is a master password. Only copy to the clipboard the password for the first argument if the master password is correct.

if len(sys.argv) <2:
    print('Usage: python pw.py [account] - copy account password')
    sys.exit()
    # read the website to be used from commandline
choice = sys.argv[1]
password = psswdDict[choice]
# copy the password to the clipboard
pyperclip.copy(str(password))
spam = pyperclip.paste()
#end of the programcount)

Just do part 2. Here is the code for part 1
