Answer 2

nvm i see what you are saying

water= []

def get_last_water_value():
return water [-1]

def add_value(transaction_amount, last_transaction= [1]):
water.append ([last_transaction, transaction_amount])
print(water)

add_value (2)
add_value (last_transaction= get_last_water_value(),transaction_amount=0)
add_value (10.89, get_last_water_value())

Answer 3

now i get
[[[1], 2]]
[[[1], 2], [[[1], 2], 0]]
[[[1], 2], [[[1], 2], 0], [[[[1], 2], 0], 10.89]]
