Count value in dictionary

Question

I am trying to count the number of times a value is repeated in a dictionary.

Here is my code:

bookLogger = [
    {'BookName': 'Noise', 'Author': 'Daniel Kahneman', 'Process': 'Reading' },
    {'BookName': 'Hunting Party', 'Author': 'Lucy Foley', 'Process': 'Reading'},
    {'BookName': 'Superintelligence', 'Author': 'Nick Bostrom', 'Process': 'Not Reading'}
]

So, I'd want to count 'Reading' for example, so that it prints:

Reading = 2
Not Reading = 1

Answer 1

Use collections.Counter to automatize the counting, then a simple loop for displaying the result:

from collections import Counter

# using "get" in case a dictionary has a missing key
c = Counter(d.get('Process') for d in bookLogger) 
# {'Reading': 2, 'Not Reading': 1}

for k,v in c.items():
    print(f'{k} = {v}')

output:

Reading = 2
Not Reading = 1
