Iterate through Pandas DataFrames Efficiently in Python

In this video I'll go through some of the various methods you can use to loop through DataFrames.

The best methods to use are:
1. Don't loop! Use vectorization.
2. List Comprehensions or looping by first converting a column into a list
3. Inbuilt pandas methods (can be pretty slow)

Thanks for this. I find myself using iterrows when using conditions on some columns to extract either the entire row(s) or selected values from other columns.
