What is the scope of variables in programming?
The scope of a variable refers to the context within which it is defined and accessible. There are generally two types: local and global.
Can you explain local and global scope with examples?
Sure! A local variable is defined within a function and can only be accessed there. For example, in Python:
def my_function():
local_var = 5 # This is a local variable
print(local_var)
A global variable is defined outside any function and can be accessed anywhere in the code:
global_var = 10 # This is a global variable
def another_function():
print(global_var)
What happens if I try to access a local variable outside its function?
If you try to access a local variable outside its function, you'll get a NameError in Python, indicating that the variable is not defined.
