Sets

Main idea

Sets store unique unordered values.

Tip

Use for duplicate removal.

Watch out

Assuming order is preserved.

Sets is used in many real programs. Right now you are in Data Mastery.

Core idea:
Sets store unique unordered values.

Read the example code on this page. Then write your own short version.

Tip:
Use for duplicate removal.

Watch out for:
Assuming order is preserved.

Your challenge:
Remove duplicate names from a list.

Use the editor in the challenge lab. When your output looks correct and there is no error, press the green button to unlock the next topic.

Example code

Copy this example if it helps. Change it so it matches Sets.

# Topic: Sets
def main():
    sample = "edit me"
    # TODO: apply Sets concept here
    result = sample
    print("Result:", result)

if __name__ == "__main__":
    main()

Challenge

Remove duplicate names from a list.

Before you can finish: your output should include at least 16 characters; at least 1 non-empty line(s); no crash traceback—fix errors until the program runs cleanly.

Use Run. Read the output. Change your code until the task is done.

Starter reference

# Challenge starter for Sets
def solve():
    # Write your solution here
    pass

print("Update solve() and run")

Your code

The first Run may load Python in your browser (one-time). Later runs are faster.
