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.

1. floor division
%s
//=
a//b
<<

2. An operator to check whether two variables refer to the same object.
()
while
is
if

3. A statement that assigns a value to a variable.
int()
a%b
+
assignment

4. This keyword in the body of a conditional allows chained conditionals.
elif (Else if)
write
>=
//=

5. A logical operator which requires two expressions to both be true.
def
print
-=
and

6. Symbol to multiply things
*
<
is
file.seek()

7. assignment operator
close
=
truncate
>

8. modulus AND assignment operator
-
write
Variables
%=

9. Symbol to add things together
%
>=
+
&

10. Where the parameters go. A necessary punctuation after any function even if it's empty.
not in
file.truncate()
%d
()

11. Less than symbol
>
<
in
except

12. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
*=
^
try
<=

13. adds an item to a list
<<
and
append()
~

14. Symbol to add things together
argument variable
+
>
/=

15. square root
file.truncate()
.py
math.sqrt(a)
truncate

16. deletes an item from a list
file.truncate()
continue
and
del

17. returns the length of a string (number of characters)
append()
:
a**b
len()

18. multiply AND assignment operator
*=
str()
a//b
input()

19. Empties the file - watch out if you care about the file.
assignment
math.sqrt(a)
a%b
*truncate

20. The extension for Python scripts
/
not
.py
%

21. 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).
is not
/=
%=
|

22. A built-in function that converts integers and strings to floating-point numbers.
float
str()
except
=

23. This keyword in the body of a conditional - gives an alternative execution.
int()
round()
del
else

24. Adds something to a variable

%s
<<
for

25. turns an object into an integer
file.write(stuff)
argv
str
int()

26. A statement that displays a value on the screen.
format string
print
elif (Else if)
close

27. exponentiation
a%b
a**b
=

-
&
file.readline()
append()

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

33. Reads the contents of the file you can assign the result to a variable.
-=
