PYTHON LESSON
Logging
Logs capture runtime events by severity levels.
Use info/warning/error appropriately.
Logging sensitive data.

This lesson is about Logging. You are in the Advanced Engineering part of the course.
Main idea:
Logs capture runtime events by severity levels.
How to learn it: type a very small program first. Run it. Change one line and run again.
Tip:
Use info/warning/error appropriately.
Common mistake:
Logging sensitive data.
Your challenge:
Add structured logs to CLI calculator.
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 Logging.
# Topic: Logging
def main():
sample = "edit me"
# TODO: apply Logging concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Add structured logs to CLI calculator.
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.
