What is Percent Of Nulls

The PercentOfNulls check calculates percent of null values for each column and displays the result as a bar chart.

Generate data

import numpy as np
import pandas as pd
from deepchecks.tabular.checks.data_integrity import PercentOfNulls

df = pd.DataFrame({'foo': [1, 2, None, np.nan], 'bar': [None, 1, 2, 3]})

Run the Check

result = PercentOfNulls().run(df)
result.show()

Define a Condition

df = pd.DataFrame({'foo': [1, 2, None, np.nan], 'bar': [None, 1, 2, 3]})
check = PercentOfNulls().add_condition_percent_of_nulls_not_greater_than()
result = check.run(df)
result.show()
