Local Scope
Explore the concept of local scope in Python to understand how variables inside functions are assigned and accessed. Learn why local variables can override outer variables, how Python handles variable resolution, and the causes of common errors like NameError and UnboundLocalError. This lesson will help you manage variable scope effectively in your Python code.
We'll cover the following...
Local scope is the scope we will use the most in Python. When we create a variable in a code block, it will be resolved using the nearest enclosing scope or scopes. The grouping of all these scopes is known as the code blocks environment. In other words, all assignments are done in local scope by default. If we want something different, then you’ll need to set your variable to global or nonlocal, which we will be looking at later on in this chapter.
