Counting Criteria in Pandas Question

[perfringo]

Is there any particular reason to import ths way:

from pandas import DataFrame, read_csv
import pandas as pd

You could use .value_conts() for counting values:

>>> df = pd.DataFrame({'numbers': range(1, 6), 'letters': [*'abaca']})
>>> df
   numbers letters
0        1       a
1        2       b
2        3       a
3        4       c
4        5       a
>>> df.letters.value_counts()['a']
