Set math finds overlaps and differences quickly.
Use intersection for common elements.
Mixing union/intersection meaning.

This lesson is about Set Operations. You are in the Data Mastery part of the course.
Main idea:
Set math finds overlaps and differences quickly.
How to learn it: type a very small program first. Run it. Change one line and run again.
Tip:
Use intersection for common elements.
Common mistake:
Mixing union/intersection meaning.
Your challenge:
Find common skills between two students.
Scroll down to the challenge lab. Run your code there. When the output meets the task and the checks pass, press the green button to finish this topic.
Example code
Copy this example if it helps. Change it so it matches Set Operations.
# Topic: Set Operations
def main():
sample = "edit me"
# TODO: apply Set Operations concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Find common skills between two students.
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.
