Hello
box is a list of 3 integer items
If I write:
box.sort()
if box == [1, 2, 3]:
the program works as expected. But if I write:
if box.sort() == [1, 2, 3]:
it doesn't work, the test always fails. Why ?
Thx
sort() sorts the sequence in place, but it _returns_ None.
Your second example becomes the equivalent of:
box.sort()
if None == [1, 2, 3]:
So although your box does become sorted, it is NOT what is compared in your if
statement.
BTW, the sorted() function won't work here either. It will return the sorted sequence, but it
leaves the original unchanged.
