[Variable scope] global scope vs function scope

 

 

- when you create a variable outside a function, we say the variable was defined inside the global scope

- when you define a variable inside a function, it is available in the function scope

- variables that are defined inside a function cannot be accessed from outside of the function

 

x = 10 # gloabl scope

def f():
	x = 20 # function scope
    y = 30 
	print (x) 

print (x) # 10
f() # 20 this does not change the gobal x
print(x) # still 10
print(y) # name error
