Asking a question with if

Q: I am stuck. What can I do?

Press Hint for a nudge, read the message next to each goal, and compare your code with the lesson text. If you still need it, Show answer reveals a model solution. Try to type it yourself rather than copy it.

Q: Does my work get saved?

if lets a program decide. After if comes a question that is True or False, then a colon, then the lines to run when it is True. Those lines are indented (pushed in by 4 spaces). Comparisons: > < >= <= == (equal to) != (not equal to). Be careful: one = stores a value, two == compares.

Your task

If temperature is above 30 print Hot day.
