Help counting the total number of dictionaries inside a list that contain a specified key value

[Jon Bowlas]

Hi All,

I have the following list containing dictionaries and I would like to
be able to count the total number of dictionaries I have that contain
a certain value set for the 'level' key:

[{'mod_title': u'Introduction to Human Anatomy', 'level': u'1',
'modcode': u'ANAT1003', 'deptleveltext': u'', 'deptlevelheader':
u'Level 1 Courses', 'subj_code': u'AE'}, {'mod_title': u'Developmental
Neurobiology', 'level': u'2', 'modcode': u'ANAT2008', 'deptleveltext':
u'', 'deptlevelheader': u'Level 2 Courses', 'subj_code': u'AE'},
{'mod_title': u'Human Neuroanatomy', 'level': u'2', 'modcode':
u'ANAT2010', 'deptleveltext': u'', 'deptlevelheader': u'Level 2
Courses', 'subj_code': u'AE'}, {'mod_title': u'Human Anatomy and
Embryology', 'level': u'2', 'modcode': u'ANAT2050', 'deptleveltext':
u'', 'deptlevelheader': u'Level 2 Courses', 'subj_code': u'AE'},
{'mod_title': u'Ethics of Fertility and Embryo Research', 'level':
u'2', 'modcode': u'ANAT2099', 'deptleveltext': u'', 'deptlevelheader':
u'Level 2 Courses', 'subj_code': u'AE'}, {'mod_title': u"Man's Place
in Nature 1750-1900", 'level': u'23', 'modcode': u'HMED3001',
'deptleveltext': u'', 'deptlevelheader': u'Level 2/3 Courses',
'subj_code': u'AE'}, {'mod_title': u'Medicine, Disease and Society,
Antiquity to Renaissance ', 'level': u'23', 'modcode': u'HMED3003',
'deptleveltext': u'', 'deptlevelheader': u'Level 2/3 Courses',
'subj_code': u'AE'}, {'mod_title': u'Madness and Society', 'level':
u'23', 'modcode': u'HMED3004', 'deptleveltext': u'',
'deptlevelheader': u'Level 2/3 Courses', 'subj_code': u'AE'}]

For example I'd like to kow how many dictionaries there are with a
level 1, 2 , 23 & 3 etc. How would one go about achieveing this?

Hope someone can help.

Cheers

Jon
