To combine sum and conditional count in pandas, you can use the groupby function along with the agg function to apply multiple aggregation functions to your data. For example, if you have a DataFrame called df with columns A, B, and C, and you want to sum the values in column A where the values in column B are greater than 0, you can do the following:
import pandas as pd
# Create a DataFrame
data = {'A': [1, 2, 3, 4, 5],
'B': [0, 1, 0, 1, 0]}
df = pd.
