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. turns an object into a string
%
%r
math.sqrt(a)
str()

2. floor division AND assignment operator
in
//=
^
close

3. exponentiation
%d
math.sqrt(a)
a**b
*=

4. Modulus operator. It's the remainder after division
==
file.seek()
read
%

5. Symbol used to create comments
n
#
//=
**=

6. End header line.
**=
:
truncate
open()

7. subtract AND assignment operator
%d
>=
+
-=

8. A logical operator which negates an expression so that it returns a value of True if the expression is false.
truncate
not
open()
and

9. A data type for representing numbers with fractional values.
raise
%r
#
floating point number

10. turns an object into an integer
raise
for
append()
int()

11. Symbol to multiply things
*write(stuff)
*
*=
else

12. This keyword in the body of a conditional allows chained conditionals.
append()
a%b
elif (Else if)
*=

13. modulus AND assignment operator
%=
==
%
try

14. inserts an item inside a list at a certain index
in
read
write
insert()

15. Empties the file - watch out if you care about the file.
*truncate
=
int()
def

16. Function to empty the contents of a file - no recovery is possible
assignment
=
+=
truncate

17. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
.py
~
argv
+=

18. The keyword beginning a header that will create a loop.
for
.py
&
abs(a)

19. Evaluates to true if it finds a variable in the specified sequence and false otherwise. x in y - here in results in a 1 if x is a member of sequence y.
in
//=
or
del

20. Less than symbol
open()
*read
<
file.truncate()

21. Function to read the contents of a file
|
read
>=
#

22. assignment operator
=
is not
try
append()

23. Function to read the contents of a file
read
%
argv
floating point number

24. floor division AND assignment operator
%=
<
if
//=

25. floor division
*=
abs(a)
//=
a//b

26. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
&
%
str()
not in

27. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
int()
:
truncate
int

28. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
=
<<
round()
Variables

29. Symbol to subtract things from each other
#
-
=
+

30. Create a variable.
*truncate
=
write
