collections.Counter object for Pandas column

I have a pandas dataframe with a column reporting a certain number of cities. I need to count the frequency of each city occurrence and put that in a collections.Counter object.

The dataframe is like this:


New York

My collections.Counter objects should then look something like this: ({'New York': 1, 'Tokyo': 2, 'Beijing': 1,...}). Is there a way to do this?

(I stress that the output has to be a collections.Counter object.)


As Chris commented, you can use use Counter(df.col1):

>>> import pandas as pd
>>> df = pd.DataFrame({ 'col1': ['New York', 'Tokyo', 'Tokyo', 'Beijing'] })

>>> from collections import Counter
>>> Counter(df.col1)

Counter({'New York': 1, 'Tokyo': 2, 'Beijing': 1})
