pandas-df-variable-name (PD901)

Derived from the pandas-vet linter.

What it does

Checks for assignments to the variable df.

Why is this bad?

Although df is a common variable name for a Pandas DataFrame, it's not a great variable name for production code, as it's non-descriptive and prone to name conflicts.

Instead, use a more descriptive variable name.

Example

import pandas as pd

df = pd.read_csv("animals.csv")

Use instead:

import pandas as pd

animals = pd.read_csv("animals.csv")
