Method chaining is a known way to improve code readability and often referred to as a Fluent API [1, 2]. Pandas does support this approach as multiple method calls can be chained like: #!/usr/bin/env python3 # -*- coding: utf-8 -*- import numpy as np import pandas as pd d = {‘col1’: [1, 2, 3, 4],… Read More Access previous dataframe during pandas method chaining
