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.

1. Less than or equal to symbol
<=
in
abs(a)
write

2. This keyword in the body of a conditional - gives an alternative execution.
else
*=
del
/=

3. floor division
round()
elif (Else if)
a//b
*write(stuff)

4. assignment operator
in
open()
=
math.sqrt(a)

5. An operator that removes a value from a list.
n
print
<
del

6. Symbol to divide by the number to the right of the symbol

%=
/
else

7. Empties the file - watch out if you care about the file.
+
truncate
readline
*truncate

8. returns the length of a string (number of characters)
.py
+
%s
