Group/Count list of dictionaries based on value

Question

I\'ve got a list of Tokens which looks something like:

[{
    Value: \"Blah\",
    StartOffset: 0,
    EndOffset: 4
}, ... ]

What I want to do

Answer 1

token = [{
    'Value': "Blah",
    'StartOffset': 0,
    'EndOffset': 4
}, ... ]

value_counter = {}

for t in token:
    v = t['Value']
    if v not in value_counter:
        value_counter[v] = 0
    value_counter[v] += 1

print value_counter
