What are StudyGrid Python Labs?

Python Labs are bootcamp-style problems at /python/labs. The question, examples, and a folded hint sit on the left. You write Python on the right, press Run or Preview, then Check. You can open the correct code if you get stuck.

Should I run countdown examples locally for better learning?

Yes. Use the browser editor on StudyGrid for a quick check, then Download the example and run it on your computer. Local runs show real errors and the real toolchain, which is one of the fastest ways to learn countdown in this Python Labs Python lesson (Countdown).

How does Check work in Python Labs?

Check grades your work with the in-browser Python worker. If every test passes, the lab is marked complete in this browser.

Can I see a hint or the correct Python solution?

Yes. Hint and Show correct code stay closed until you open them. You can load the solution into the editor and still press Check.

Do I need to install extra software for Python Labs?

No. Labs run in the browser, the same way the Python editor does at /try.

Is the Python bootcamp free?

Yes. The labs on StudyGrid (studygrid.in) are free. Progress is stored in this browser only.

Read the question, write Python on the right, then Run or Check.

QuestionHint and solution stay closed until you open them

Read n and print the numbers from n down to 1, space-separated on one line.

range can count backwards: range(n, 0, -1).

Input. One line: an integer n ≥ 1.

Output. n space-separated integers, descending.

Constraints

1 ≤ n ≤ 50

Examples

Example 1

Input

Output

5 4 3 2 1

Hint

range(n, 0, -1) yields n, n-1, …, 1.
print(*range(n, 0, -1)) does the whole job.

Show correct code

Peek only after you have tried. You can still Check your own version.

n = int(input())
print(*range(n, 0, -1))

main.pyPython · Ctrl + Enter runs

Program input (stdin) — used by input()
