Tank Sorting

Again in the context of the water tanks from the previous problem, you are required to deliver the following sorting functions in the module tank_sorting (file tank_sorting.py).

---

The first function is:

tank_sort_1(tL)

such that

given tL a list of of water tank info as described above

returns a copy of tL but where that the tanks are ordered by placing first the tanks with more water contributions. In case of a tie the order in Lt is maintained.

For example:

>>> tanksL = [
... ['Carmel', 20, [2, 3, 4, 1, 5, 1]],
... ['Nou_Barris', 10, [1, 2, 1, 5, 10]], 
... ['Sant_Pere_Martir', 15, [2, 4, 8, 4, 2, 5, 7, 4]], 
... ]
>>> newtanksL = tank_sort_1(tanksL)
>>> newtanksL == [
... ['Sant_Pere_Martir', 15, [2, 4, 8, 4, 2, 5, 7, 4]], 
... ['Carmel', 20, [2, 3, 4, 1, 5, 1]],
... ['Nou_Barris', 10, [1, 2, 1, 5, 10]], 
... ]
True

Doctests are available in the tank_sort_1.test file.

The second function is:

tank_sort_2(tL)

such that

given tL a list of water tank info as described above

rearranges tL by placing first the tanks with higher capacity. The tanks with the same capacity must be alphabetically ordered.

For example:

>>> tanksL = [
... ['Carmel', 20, [2, 3, 4, 1, 5, 1]],
... ['Nou_Barris', 10, [1, 2, 1, 5, 10]], 
... ['Sant_Pere_Martir', 15, [2, 4, 8, 4, 2, 5, 7, 4]], 
... ['N3', 10, [2, 3, 4, 1, 5, 1]],
... ['N2', 10, [1, 2, 1, 5, 10]], 
... ['Sant_Antoni', 15, [2, 4, 8, 4, 2, 5, 7, 4]],
... ]
>>> tank_sort_2(tanksL)
>>> tanksL == [
... ['Carmel', 20, [2, 3, 4, 1, 5, 1]],
... ['Sant_Antoni', 15, [2, 4, 8, 4, 2, 5, 7, 4]],
... ['Sant_Pere_Martir', 15, [2, 4, 8, 4, 2, 5, 7, 4]], 
... ['N2', 10, [1, 2, 1, 5, 10]], 
... ['N3', 10, [2, 3, 4, 1, 5, 1]],
... ['Nou_Barris', 10, [1, 2, 1, 5, 10]], 
... ]
True

Doctests are available in the tank_sort_2.test file.
