df.describe() and skew are the first look. Nairobi rows are comments, not a string column required.

Goal

Describe a five-row shillings series.

import pandas as pd
s = pd.Series([126.0, 198.0, 93.0, 73.5, 242.0])
print(s.describe())
print('skew', round(s.skew(), 3))

import pandas as pd
df = pd.DataFrame({'units': [12, 9, 3, 7], 'shillings': [126, 198, 93, 73.5]})
print(df.corr())

import pandas as pd
print(pd.Series([80, 60, 110, 90]).mean())

import pandas as pd
print(pd.Series([12, 9, 3, 7, 11]).quantile([0.25, 0.5, 0.75]))
