What is Scope in Python?

Answer»

Every OBJECT in Python functions within a scope. A scope is a block of code where an object in Python remains relevant. Namespaces uniquely IDENTIFY all the objects inside a program. However, these namespaces also have a scope defined for them where you could use their objects without any prefix. A few EXAMPLES of scope CREATED during code execution in Python are as follows:

  • A local scope refers to the local objects available in the CURRENT function.
  • A global scope refers to the objects available throughout the code execution since their inception.
  • A module-level scope refers to the global objects of the current module accessible in the program.
  • An outermost scope refers to all the built-in names callable in the program. The objects in this scope are searched last to find the name referenced.

Note: Local scope objects can be synced with global scope objects using keywords such as global.
