- improving the student's skills in operating with the
deepcopy()method on a list of dictionaries.
Scenario
IntroductionImagine you have been hired to help run a candy warehouse.
The task- Your task is to write a code that will prepare a proposal of reduced prices for the candies whose total weight exceeds 300 units of weight (we don’t care whether those are kilograms or pounds)
- Your input is a list of dictionaries; each dictionary represents one type of candy. Each type of candy contains a key entitled 'weight', which should lead you to the total weight details of the given delicacy. The input is presented in the editor;
- Prepare a copy of the source list (this should be done with a one-liner) and then iterate over it to reduce the price of each delicacy by 20% if its weight exceeds the value of 300;
- Present an original list of candies and a list that contains the proposals;
- Check if your code works correctly when copying and modifying the candy item details.
Expected output
Source list of candies
{'name': 'Lolly Pop', 'price': 0.4, 'weight': 133}
{'name': 'Licorice', 'price': 0.1, 'weight': 251}
{'name': 'Chocolate', 'price': 1, 'weight': 601}
{'name': 'Sours', 'price': 0.01, 'weight': 513}
{'name': 'Hard candies', 'price': 0.3, 'weight': 433}
******************
Price proposal
{'name': 'Lolly Pop', 'price': 0.4, 'weight': 133}
{'name': 'Licorice', 'price': 0.1, 'weight': 251}
{'name': 'Chocolate', 'price': 0.8, 'weight': 601}
{'name': 'Sours', 'price': 0.008, 'weight': 513}
{'name': 'Hard candies', 'price': 0.24, 'weight': 433}
If your code issues the same output, then you deserve a small reward:
Code
warehouse = list()warehouse.append({'name': 'Lolly Pop', 'price': 0.4, 'weight': 133})
warehouse.append({'name': 'Licorice', 'price': 0.1, 'weight': 251})
warehouse.append({'name': 'Chocolate', 'price': 1, 'weight': 601})
warehouse.append({'name': 'Sours', 'price': 0.01, 'weight': 513})
warehouse.append({'name': 'Hard candies', 'price': 0.3, 'weight': 433})
print('Source list of candies')
for item in warehouse:
print(item)
