Find the Second Largest Value
Removing duplicates before sorting makes the desired rank unambiguous.
What is Find the Second Largest Value?
Removing duplicates before sorting makes the desired rank unambiguous.
Find the second distinct largest list value.
When should you use it?
- Learn Python syntax through a practical example.
- Build a foundation for larger programming problems.
- Test an idea quickly without a local setup.
Example code
main.py
values = [7, 23, 12, 23, 9]
# Remove duplicates before selecting the second-highest rank.
distinct = sorted(set(values))
print(f"second={distinct[-2]}")Expected output
second=12How it works
A set keeps distinct values and sorted places the largest values at the end.
Change the values and run the program in the CodeUtility online Python compiler without installing Python locally.
Practice exercises

- Change the input and predict the output before running.
- Handle empty or invalid input.
- Wrap the logic in a function and add more test cases.
