DataFrame in Python

A DataFrame is a dict of Series that share one index.

import pandas as pd

frame = pd.DataFrame({
    "lang": ["python", "rust", "sql"],
    "tours": [11, 12, 3],
    "tpm": [104.5, 98.0, 88.5],
})

print(frame.shape, list(frame.columns))
print(frame.dtypes)
print(frame.head(2))
print(frame.describe().round(2))

How it works

1. Building from a dict makes each key a column.
2. shape, columns and dtypes describe it.
3. head is how you look without printing everything.
