Description

In a program of any complexity, you’ll create hundreds or thousands of names, each pointing to a specific object. How does Python keep track of all these names so that they don’t interfere with one another? This course covers Python namespaces, the structures used to organize the symbolic names assigned to objects in a Python program.

In this course, you’ll learn:

What You'll Learn?

How Python organizes symbolic names and objects in namespaces
When Python creates a new namespace
How namespaces are implemented
How variable scope determines symbolic name visibility
What is the LEGB rule

Hallo, my name is Johan, and I am a software engineer working for the Pythoneers at Ordina in the Netherlands. I have a soft spot for awesome software design, clean code and sharing knowledge.

My goal is to share knowledge I gained in over the years to anyone who wants to learn, which I do through my blog, YouTube, MeetUps and here on Real Python.

Even though Python is the primary language I use on the job, I do think it is important to pick the right tool for the job. So next to Python I can work with C#, Java and Javascript.

You are most welcode to follow me on GitHub, LinkedIn or Twitter.

Some of the online meetups I contributed to:
