Because local name lookup is faster than global name lookup. Local
variables are stored in an array in the stack fr
In the following snippet, the loop in the global namespace takes twice as long
as the loop in the function namespace. Why?
limit = 5000

counter = 0
while counter < limit:
counter += 1
time1 = time.time()
f1()
print(time.time() - time
