In this port you see how to calculate ratio in Pandas.

## Ratio calculations

You can calculate the ratio between two columns of a pandas DataFrame using the following code:

import pandas as pd df = pd.DataFrame({'col1': [1, 2, 3, 4, 5], 'col2': [10, 20, 30, 40, 50]}) df['ratio'] = df['col1'] / df['col2']

In this example, the ratio between col1 and col2 is calculated and stored in a new column called ratio. The result will be a DataFrame with three columns: col1, col2, and ratio.
