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. A logical operator which compares two operands and produces True if they are equal and False otherwise
*read
str()
return
==

2. Function to close a file - it will not be able to be used again unless the file is opened.
close
str()
round()
except

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

4. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
floating point number
&
append()
def

5. multiply AND assignment operator
/
*=
file.truncate()
in

6. rounds a number to the number of decimal points you choose
round()
<=
*
a**b

7. Less than symbol
read
for
<
readline

8. Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. a << 2 will give 240 which is 1111 0000
for
insert()
<<
is

9. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
float
**=
~
>>

10. Symbol used to create comments
abs(a)
/
in
#

11. sets the file's current position
%r
read
file.seek()
else

12. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
Variables
break
>
or

13. The keyword beginning a header that will create a loop.
**=
for
del
=

14. inserts an item inside a list at a certain index
a//b
%r
=
insert()

15. Function to close a file - it will not be able to be used again unless the file is opened.
*readline
print()
%s
close

16. 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
n
print()
a**b

17. Symbol to multiply things
*
int()
*truncate
#

18. This statement causes an exception.
*write(stuff)
raise

//=

19. Symbol to add things together
+
n
break
float

20. End header line.
*truncate
:
insert()
%d

21. divide AND assignment operator
close
*=
&
/=

22. Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. a >> 2 will give 15 which is 0000 1111
#
>>
<<
+=

23. floor division
//=
|
a//b
=

24. Binary XOR Operator copies the bit if it is set in one operand but not both. (a ^ b) will give 49 which is 0011 0001
Variables
^
math.sqrt(a)
*=

25. square root
append()
len()
math.sqrt(a)
print()

26. turns an object into an integer
continue
float
truncate
int()

27. This keyword begins the simplest form of a conditional statement.
%=
file.write(stuff)
return
if

28. Less than symbol
#
round()
-
<

29. Create a variable.
&
-=
and
=

30. This keyword in the body of a conditional - gives an alternative execution.
else
*
-
%r

31. 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.
**=
while
argument variable
**=

32. 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).
or
*read
a%b
is not

33. Greater than or equal symbol.
<
>=
%s
round()

34. Reads just one line of a text file.
>>
*readline
/
**=

35. divide AND assignment operator
~
def
~
/=

36. A statement that assigns a value to a variable.
a**b
a%b
is
assignment

37. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
>=
