PYTHON LESSON
User Input
input() always returns text unless converted.
Validate before converting.
Assuming numeric input.

User Input is used in many real programs. Right now you are in Foundations.
Core idea:
input() always returns text unless converted.
Read the example code on this page. Then write your own short version.
Tip:
Validate before converting.
Watch out for:
Assuming numeric input.
Your challenge:
Build a Celsius/Fahrenheit converter using input.
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 User Input.
# Topic: User Input
def main():
sample = "edit me"
# TODO: apply User Input concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Build a Celsius/Fahrenheit converter using input.
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.

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