Series in Python

A Series is a column: values plus an index that travels with them.

import pandas as pd

runs = pd.Series([91, 104, 88], index=["mon", "tue", "wed"], name="tpm")

print(runs)
print(runs["tue"], runs.iloc[0])
print(runs.mean().round(1), runs.max())
print(runs + pd.Series([1, 1], index=["mon", "wed"]))

How it works

1. The index is the label, not just a position.
2. Arithmetic aligns on the index, it does not zip by position.
3. dtype is one type for the whole column.
