Difficulty level:

иконка человека красный иконка человека белая иконка человека зеленая Pythonlib

Task«Summer of all elements of the matrix»

You work in an online store and you need to create a system for sorting goods according to various criteria. Each product has a name, price and rating. It is necessary to realize a higher order function that creates specialized sorters for a list of goods.
rn
The function should take the design criterion (name, price or rating) and direction (by increasing or decreasing), and return the function-sorter that sorts the list of goods according to the specified parameters.

Input format

The first line contains the amount of goods n.

the last line contains a criterion of sorting and a direction: criterion: name/price/rating, direction: ASC/DesC)

Output format

sorted list of goods, each product on a separate line in format: name the price rating

Example

Input

4
Laptop 50000 4.5
Mouse 1500 4.2
Keyboard 3000 4.8
Monitor 25000 4.1
Price asc

Output

mouse 1500 4.2
Keyboard 3000 4.8
Monitor 25000 4.1
Laptop 50000 4.5

How to Solve Tasks?

1 - Read the task and understand what needs to be done

2 - The example shows how the input data will be provided and what output is expected

3 - Write the code considering the input, output, and the task itself.

(see example below)

Difference Between the "Run" and "Test on All Cases" Buttons

1 - The “Run” button executes your code only on one set of input data, and you’ll see the result in the output window.

2 - The “Test on All Cases” button runs your code against all test cases. If all tests pass, a banner will appear. If even one test fails, it will be highlighted in red.

(see example below)

How to Change Input Data

To change the input data, click the “Run Test” button next to the input data you want to execute.

(see example below)

Working with Input/Output Windows

1 - Input Data is the window containing the values loaded into your program in place of input()

2 - Program Output is the window showing what your program prints. If it’s green, the output matches the expected result; if red, there are differences.

3 - Expected Output is the reference value used to verify the solution.

(see example below)

Guide to the "Run Test" Button

1 - Green means the program produced the correct output

2 - Red means the program’s output didn’t match the expected output for this data. The program output and the expected output must be identical, including spaces and punctuation!

Criteria for a Correct Solution — How to Know It’s Right

If you see this banner, congratulations — everything is correct.

Topic Structure (30 Tasks: 10 Easy, 10 Medium, 10 Hard)

1 - The first 10 tasks are quite easy and contain hints covering only the essential parts of the topic.

2 - The next 10 tasks are medium difficulty. Their hints differ from the easy ones and reveal new aspects of the topic.

3 - The hardest tasks have no hints. Often, they include additional topics, so sometimes it’s better to move on and return later. Read the hints carefully — they offer new ways to solve already familiar problems.

(see example below)

Availability of Theory (Video + Text)

1 - Each block contains a “Theory” section.

2 - It always includes a detailed video.

3 - There is also a detailed guide with all the necessary theory and code examples.
