In which order are the for parts written?
Short answer. Outer loop first, then inner.
What does the output contain?
['A1', 'A3', 'B1', 'B3'].
Remember
| Outer for first, inner next |
| if at the end filters |
Two loops and a condition in one line? Yes. Here a is the row and b is the seat. The outer loop comes first. The check skips seat two. We get A one, A three, B one, B three. Outer for first. An if at the end filters.
