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. Evaluates to true if it does not finds a variable in the specified sequence and false otherwise. x not in y - here not in results in a 1 if x is a member of sequence y.
<<
a//b
()
not in

2. subtract AND assignment operator
a**b
-=
truncate
else

3. The extension for Python scripts
write
:
%d
.py

4. add AND assignment operator
+=
is not
read
=

5. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
print
and
#
read

6. 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
truncate
argv
<<
^

7. Less than or equal to symbol
>>
>
<=
argv

8. Prints a string to the screen which will be Unicode.
>=
%s
read
insert()

9. A logical operator which negates an expression so that it returns a value of True if the expression is false.
readline
<<
not
return

10. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
readline
|
else
not

11. prints its parameter to the console
read
print()
for
while

12. Prints a string to the screen which is converted using repr()
%r
len()
n
%d

13. divide AND assignment operator
elif (Else if)
>>
truncate
/=

14. Symbol to divide by the number to the right of the symbol
assignment
-
/
not

15. The keyword beginning a header that will create a loop.
&
del
abs(a)
for

16. Greater than symbol
>
truncate
()
/

17. Prints a string to the screen which is a signed decimal.
n
readline
**=
%d

18. The keyword beginning a header that will create a new function.
del
def
>
if

19. reads just one line of a text file & keeps track of where in the file you're at
str()
+
int()
file.readline()

20. Less than or equal to symbol
while
=
<=
%=

21. Less than symbol
in
<
<=
if

22. Function to write something to a file
math.sqrt(a)
+
write
>

23. modulus AND assignment operator
input()
append()
**=
%=

24. Where the parameters go. A necessary punctuation after any function even if it's empty.
*readline
insert()
()
file.seek()

25. 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
in
>>
<<
not in

26. Modulus operator. It's the remainder after division
a//b
%
%=
%s

27. floor division
~
else
a//b
not in

28. subtract AND assignment operator
write
round()
file.readline()
-=

29. This keyword in the body of a conditional allows chained conditionals.
elif (Else if)
*truncate
raise
*readline

30. Function to empty the contents of a file - no recovery is possible
truncate
^
def
*

31. Adds a new line character
raise
n
str
<

32. returns the length of a string (number of characters)
+=
len()
=
()

33. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
-=
int
=
Variables

34. A statement that breaks out of a loop.
abs(a)
while
break
%r

35. empties the file
print
and
^
file.truncate()

36. 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
*readline
read
def

37. Symbol to add things together
-=
argument variable
+
print

38. absolute value
def
and
*
abs(a)

39. exponent AND assignment operator
%s
**=
%=
=

40. A statement that displays a value on the screen.
print
if
print()
/=

41. 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
=
()
>>
class

42. Symbol used to create comments
str
