coinexplorer.check_password(passwd)

Basic authentication for accessing features that only the instructor should access (like erasing list of pending transactions or changing difficulty)

The hidden symbol _password in module coinexplorer is the md5 hash of the actual password. To change the password to something else, say for example KoalaBear you would:

>>>  import hashlib
>>>  hashlib.md5("KoalaBear").hexdigest()
'd445aa703dabaf0159ac02947793874f'

and set _password = 'd445aa703dabaf0159ac02947793874f' in module coinexplorer

Note that this is not a very secure way of doing things, as the password is sent in clear text and may just appear in the browsing history.

Return type:bool Returns:True if passwd matches the password
