Derived from the pandas-vet linter.

What it does

Checks for uses of pd.read_table to read CSV files.

Why is this bad?

In the Pandas API, pd.read_csv and pd.read_table are equivalent apart from their default separator: pd.read_csv defaults to a comma (,), while pd.read_table defaults to a tab (\t) as the default separator.

Prefer pd.read_csv over pd.read_table when reading comma-separated data (like CSV files), as it is more idiomatic.

Example

import pandas as pd

cities_df = pd.read_table("cities.csv", sep=",")

Use instead:

import pandas as pd

cities_df = pd.read_csv("cities.csv")
