What is the difference between scope and lifetime in Python?
An example of an AI chatbot conversation about understanding Python's scope and lifetime concepts.
What is the difference between scope and lifetime in Python?
In Python, scope refers to the visibility of variables, while lifetime refers to how long a variable exists in memory.
Can you give me an example of scope in Python?
Sure! In Python, a variable defined inside a function is local to that function and cannot be accessed outside of it.
What about global variables? How do they fit into scope?
Global variables are accessible from anywhere in the code, including inside functions, unless shadowed by a local variable.
And how does lifetime affect garbage collection?
Lifetime affects garbage collection because variables that are no longer in scope or referenced can be collected by Python's garbage collector.
