passwords={'emails':'' 'F7minlBDDuvMJuxESSKHFhTxFtjVB6',
           'blog':'VmALvQyKAxiVH5G8v01if1MLZF3sdt',

if len(sys.argv)<2:
    print('usage:python python3文件[accout]-copy accout password')
    sys.exit()

accout=sys.argv[1]  # frist command line arg is the accout name

if accout in passwords:
    pyperclip.copy(passwords[accout])
    print('Password for ' + accout + ' copied to clipboard')

else:
    print('There is no accout named ' + accout)

添加批处理脚本：

@D:\python\python.exe D:\pythonpassword\pythonpassword.py %*
@pause

添加环境变量，然后直接win+R，输入pw+ 需要的账户，就能提取到对应的密码，直接可以执行粘贴，方便平常输入密码。
