What are the basic scoping rules for python variables?

PythonServer Side ProgrammingProgramming

In the book Learning Python by Mark Lutz, he suggests the following mnemonic for remember how Python scoping works: LEGB

Going from the narrowest scope to the widest scope:

L stands for “Local”. It refers to variables that are defined in the local scope of functions.

E stands for “Enclosing”. It refers to variables defined in the local scope of functions wrapping other functions. G stands for “Global”. These are the variables defined at the top level of files and modules.

B stands for “Built in”. These are the names that are loaded into scope when the interpreter starts up.
