Operators

Main idea

Operators tell Python what operation to perform between values.

Tip

Test operators in tiny examples.

Watch out

Confusing = and ==.

Operators is used in many real programs. Right now you are in Foundations.

Core idea:
Operators tell Python what operation to perform between values.

Read the example code on this page. Then write your own short version.

Tip:
Test operators in tiny examples.

Watch out for:
Confusing = and ==.

Your challenge:
Build a mini calculator for +, -, *, /.

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 Operators.

# Topic: Operators
def main():
    sample = "edit me"
    # TODO: apply Operators concept here
    result = sample
    print("Result:", result)

if __name__ == "__main__":
    main()

Challenge

Build a mini calculator for +, -, *, /.

Before you can finish: your output should include at least 12 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.

Starter reference

# Challenge starter for Operators
def solve():
    # Write your solution here
    pass

print("Update solve() and run")

Your code

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