Type Casting
Casting converts values into the required data type.
Cast user input immediately.
Converting invalid text to int without checks.

You will study Type Casting. It belongs to the Foundations phase.
Remember this:
Casting converts values into the required data type.
Practice step by step. Do not rush. Each run should show you something new.
Tip:
Cast user input immediately.
Avoid this:
Converting invalid text to int without checks.
Your challenge:
Take two string numbers, convert, and print the sum.
Go to the challenge lab below. Fix errors until the output looks right. Then press the green button to complete the topic.
Example code
Copy this example if it helps. Change it so it matches Type Casting.
# Topic: Type Casting
def main():
sample = "edit me"
# TODO: apply Type Casting concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Take two string numbers, convert, and print the sum.
Before you can finish: your output should include at least 14 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.
