The dataset looks roughly like the following example: import pandas as pd import numpy as np rng = np.random.RandomState(0) df = pd.DataFrame({'Patient': ['A','A','A','B','B','B','C','C','C'], 'Visit': [1,2,3,1,2,3,1,2,3], 'Parameter': r...
dataSet.isnull().sum(axis = 0)Note: axis = 0 instructs pandas to go through all the rows column-wise.You should see the following output:C1 4 C2 1 C3 2 C4 3 dtype: int64Columns (which will eventually represent features or variables in data science/machine learning projects) with large...
