The problem with the current approach is that you are modifying the original list dcm by using row.pop(-1) and then appending item to the row. This changes the order of elements in each row, which may not be what you want. To fix this issue, you can create a copy of the original list and modify the copy instead of the original list. Here’s how you can do it: import csv dcm = [ ['00004120-13e4-11eb-874d-637bf9657209', 2, [2.

Handling Large Data with Pandas and Dictionaries: An Efficient Approach When dealing with large datasets, it’s essential to understand the trade-offs between different data structures and their computational efficiency. In this article, we’ll explore the use of dictionaries to efficiently handle large pandas DataFrames. Understanding Pandas DataFrames A pandas DataFrame is a two-dimensional labeled data structure with columns of potentially different types. It provides efficient data manipulation and analysis capabilities. However, when dealing with extremely large datasets, traditional methods can become computationally expensive.
