Filter list of dictionaries

Question

This is my example:

dictlist = [{\'first\': \'James\', \'last\': \'Joule\'}, 
            {\'first\': \'James\',\'last\': \'Watt\'},
            {\'first\':          


        

Answer 1

This is very simple solution with list comprehension:

>>> dictlist = [{'first': 'James', 'last': 'Joule'}, {'first': 'James','last': 'Watt'},{'first': 'Christian','last': 'Doppler'}]
>>> [x['last'] for x in dictlist if x['first'] == 'Christian']
['Doppler']
