A debugger is useful for more than debugging; it can also help give an
intuition for control flow. If you single step through this snippet with a
debugger, you'll probably see what's happening.
Of if you don't have (or want) a debugger, you could change it to:
var = 0
for i in range(3):
print('i is', i)
for j in range(-2,-7,-2):
print('j is', j)
var += 1
print(var)
And note that 3 times 3 is 9.
