Message244898
The behaviour is correct, this is not a bug. Each time you pop from aa, the following items move down one space. Then, the next time you pop, the items have moved:
['a0', 'b1', 'c2', 'd3', 'e4', 'f5', 'g6', 'h7', 'i8', 'j9', 'k10', 'l11']
d3 is the third item and gets popped;
['a0', 'b1', 'c2', 'e4', 'f5', 'g6', 'h7', 'i8', 'j9', 'k10', 'l11']
g6 is the fifth item and gets popped;
['a0', 'b1', 'c2', 'e4', 'f5', 'h7', 'i8', 'j9', 'k10', 'l11']
j9 is the seventh item and gets popped.
To get the result you want, you can use slicing:
aa[3:9:2]
=> returns ['d3', 'f5', 'h7']
then
del aa[3:9:2]
=> leaves ['a0', 'b1', 'c2', 'e4', 'g6', 'i8', 'j9', 'k10', 'l11'] |
