Pandas DataFrame gt() method with examples

The gt() method compare each value in a DataFrame to check if it is greater than a specified value, or a value from a specified DataFrame objects, and returns a DataFrame with boolean True/False for each comparison.

Syntax –

DataFrame.gt(other, axis='columns', level=None)

other – Any single or multiple element data structure, or list-like object.

axis – Whether to compare by the index (0 or ‘index’) or columns (1 or ‘columns’).

level – Broadcast across a level, matching Index values on the passed MultiIndex level.

Examples –

Let’s create a dataframe

import pandas as pd

data = {'Apple':[89, 89, 90, 110, 125, 84, 131, 123, 123, 140, 145, 145],
       'Orange': [46, 46, 50, 65, 63, 48, 110, 120, 60, 42, 47, 62],
       'Banana': [26, 30, 30, 25, 38, 22, 22, 36, 20, 27, 23, 34 ],
       'Mango': [80, 80, 90, 125, 130, 150, 140, 140, 135, 135, 80, 90]}

index = ['Jan','Feb','Mar','Apr','May','June','Jul','Aug','Sep','Oct','Nov','Dec']
df = pd.DataFrame(data, index=index)
df

1 . Comparing a DataFrame with a single value using DataFrame.gt() method –

Let’s say you want to know which values in the dataframe are greater than 100.

df.gt(100)

2 . Comparing a series with another series using DataFrame.gt() method –

You can also compare a series with another series using the gt() method.

df['Apple'].gt(df['Mango'])
