Access level by level.
Losing track of nesting depth.

This lesson is about Nested Structures. You are in the Data Mastery part of the course.
Main idea:
Lists and dicts can nest to represent real data.
How to learn it: type a very small program first. Run it. Change one line and run again.
Tip:
Access level by level.
Common mistake:
Losing track of nesting depth.
Your challenge:
Company data lookup by department and employee.
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 Nested Structures.
# Topic: Nested Structures
def main():
sample = "edit me"
# TODO: apply Nested Structures concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Company data lookup by department and employee.
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.
