Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

def
+=
break

int()
%=
a%b
class

5. Less than or equal to symbol
<=
write
*readline
format string

6. multiply AND assignment operator
argument variable
+
*=
%=

7. This keyword begins a header for a body that repeats until the condition is no longer true.
while
append()
close
and

8. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
