Python: Iterate Through Dictionary And Create List With Results

I would like to iterate through a dictionary in Python in the form of: dictionary = { 'company': { 0: 'apple', 1: 'berry', 2: 'pear' }, 'co

Solution 1:

I suppose your keys are strings as well and the output is a list of lists, where the elements are strings, too. Then this problem can be solved via list comprehension.

The idea is to use list comprehension to fill the list of [company, country]-lists, but only if the country is 'US'. key represents the keys of the inner dictionaries (i.e 0, 1, 2).

dictionary = {'company': {0: 'apple', 1: 'berry', 2: 'pear'}, 'country': {0: 'GB', 1: 'US', 2:'US'}}
y = [[dictionary['company'][key], dictionary['country'][key]] for key in dictionary['country'] if dictionary['country'][key] == 'US']

It returns

[['berry', 'US'], ['pear', 'US']]

Solution 2:

myList = []
list(map(lambda x: myList.append(x) if x[1]=='US'elseNone,
    zip(dictionary['company'].values(), dictionary['country'].values())))
