data = {'A': [10, 20, 30, 40, 50], 'B': [3, 5, 7, 9, 11]}
df = pd.DataFrame(data)
# Perform floor division on the columns
df['A_div_B'] = df['A'] // df['B']
print(df)
The yield will be:
A B A_div_B
0 10 3 3
1 20 5 4
2 30 7 4
3 40 9 4
4 50 11 4
In this example, the Double Slash Python manipulator is used to perform floor part on the columns of a DataFrame. This ensures that the results are always integers, qualification it easier to work with in information analysis.
