>>> calculate_total(price_list)
Homework Answers
In this Python program
- We have defined a function called calculate_total which accepts a list and returns an int variable.
- In the list price_list, we have a list of lists which needs to satisfy 2 conditions one of them is it should have length 2 and also the 2nd element in the sublist should be an int
- Only those sublists which satisfy the above 2 conditions, those 2nd elements in the sublist got summed up
- Finally we are returning the int variable called sum as an output
Program:
def calculate_total(price_list: list) -> int:
sum=0
for i in price_list:
if( len(i)==2 and isinstance(i[1], int) ):
sum=sum+i[1]
return sum
price_list = [["apple", 1], ["sugar", 5], ["mango", 3],
["coffee", 9], ["trail mix", 6]]
print(calculate_total(price_list))
