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.

23. Prevents a runtime error from stopping the program.
except
math.sqrt(a)
file.seek()
print

24. This variable holds the arguments you pass to your Python script when you run it. Then you unpack it in your script so you have variables you can work with.

in
read

40. exponentiation
<<
del
floating point number
a**b

41. Evaluates to false if the variables on either side of the operator point to the same object and true otherwise. x is not y - here is not results in 1 if id(x) is not equal to id(y).
for
is not
%s
if

42. absolute value
