python count the number of zeros in each row of a pandas dataframe
# Basic syntax: (pandas_dataframe == 0).sum(axis=1) # Where axis 1 specifies that sum will operate on rows. Use 0 for columns # Example usage: # Create Pandas dataframe: import pandas as pd pandas_dataframe = pd.DataFrame({'a':[1,0,0,1,3], 'b':[0,0,1,0,1], 'c':[0,0,0,0,0]}) a b c 0 1 0 0 1 0 0 0 2 0 1 0 3 1 0 0 4 3 1 0 (pandas_dataframe == 0).sum(axis=1) 0 2 1 3 2 2 3 2 4 1
