There are several ways to add a variable to a Python dataframe ...

But my preferred way is the Pandas "assign" method.

The Pandas assign method has fairly simple syntax.

You can use the technique to add a single new variable like this:

You can also use the assign method to add multiple new variables at the same time.

This is very convenient if you need to do a lot of data wrangling.

If you're doing data wrangling or data cleaning, the assign method becomes even more powerful if you use it in a "chain" of other Pandas methods.

Techniques like the Pandas assign method seem simple, and they are at first.

But once you learn how to use them in simple ways, you can learn to use them in complex ways.

This is the secret to more advanced data analysis and data science.

Learn the basics, then learn how to use them in complex ways.
