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.

Variables
/=

2. exponentiation
*
Variables

a**b

3. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
%

~
print()

4. assignment operator
+
#
else

5. 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.
del
append()
<<
argument variable

6. Reads just one line of a text file.
~
()
/=
*readline

7. exponentiation
else
<<
a**b
len()

8. floor division
a//b
**=
format string
str()

9. This keyword begins the simplest form of a conditional statement.
file.seek()
()
//=
if

16. Function to write something to a file
write
