By using the pprint module you can examine the contents of an element.

from pprint import pprint

pprint(vars(element))

Using this on a bs4 element will print something similar to this:

{'attrs': {u'class': [u'pie-productname', u'size-3', u'name', u'global-name']},
 'can_be_empty_element': False,
 'contents': [u'\n\t\t\t\tNESNA\n\t'],
 'hidden': False,
 'name': u'span',
 'namespace': None,
 'next_element': u'\n\t\t\t\tNESNA\n\t',
 'next_sibling': u'\n',
 'parent': 
\nBedside table\n\n\t\t\t\tNESNA\n\t\n
,
 'parser_class': ,
 'prefix': None,
 'previous_element': u'\n',
 'previous_sibling': u'\n'}

To access an attribute - lets say the class list - use the following:

class_list = element.attrs.get('class', [])

You can filter elements using this approach:

for script in soup.find_all('script'):
    if script.attrs.get('for'):
        # ... Has 'for' attr
    elif "myClass" in script.attrs.get('class', []):
        # ... Has class "myClass"
    else: 
        # ... Do something else
