Simple if-else question

If I'm reading the indentation correctly, the else is applying to the for
loop, not the if statement.

When used in this way, the else occurs only if the for loop exits due to
completion (aka, the for loop does not exit due to a break or return
statement).


I would expect the output from that code to be:
0
1
2
3
7

Any values in the range under 4 should be printed (the if), as well as the
last value in the range (7 in the case given).
