Iteration Data in DataFrame
Explore how to efficiently iterate through pandas DataFrames using built-in methods like iterrows, iteritems, and itertuples. Understand the performance differences and learn how to access data by row and column. This lesson will help you improve your data processing workflow by choosing the best iteration method.

Iteration is a slow operation, especially if it is done by methods like apply(). Fortunately, you can choose alternative methods given by pandas.
You still can use a normal for loop in your code to iterate a DataFrame, but keep in mind the following:
- Iteration is slow.
itertuples()is much faster in most cases.
iterrows()
When we talk about iteration, most of the ...
