Introduction to Pandas DataFrames and Looping Operations Pandas is a powerful library in Python for data manipulation and analysis. One of its key features is the ability to work with structured data, such as tables and datasets. In this article, we will explore how to run a loop within a Pandas DataFrame to append a column. Understanding the Problem Statement The problem statement involves two DataFrames: df1 and df2. The goal is to fill in the values of the ‘Usage’ column in df1 based on the logic that whenever the MID value changes, we need to look up the corresponding POSITION from df2 and assign a usage value.
