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. divide AND assignment operator
/=
^
round()
+

2. Less than symbol
*=
append()
<
is not

3. 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
file.seek()
len()

4. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.
<=
in
def
argv

5. adds an item to a list
#
>>
%d
append()

6. Adds something to a variable
=
file.seek()
*truncate
*readline

7. This keyword in the body of a conditional - gives an alternative execution.
()
%r
else
pass

8. Symbol to divide by the number to the right of the symbol
n
%
/
//=

9. A statement that breaks out of a loop.
append()
close
break
print()

10. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
write
try
abs(a)
else

11. This keyword begins the simplest form of a conditional statement.
|
if
read
:

12. Function to empty the contents of a file - no recovery is possible
truncate
<<
*=
write

13. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.

%s
else
Variables

14. exponentiation
>>
>=
a**b
input()

15. Prints a string to the screen which will be Unicode.
readline
*
%s
==

16. The keyword beginning a header that will create a loop.
//=
round()
for
/

17. Empties the file - watch out if you care about the file.
.py
%s
%d
*truncate

18. adds an item to a list
and
write
append()
class

19. 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.
argument variable
open()
append()
=

20. add AND assignment operator
pass
&
file.truncate()
+=

21. This keyword begins a header for a body that repeats until the condition is no longer true.
argv
is
while
#

22. Adds a new line character
file.readline()
n
#
print()

23. floor division AND assignment operator
//=
=
=
else

24. This statement causes an exception.
raise
for
abs(a)
#

25. square root
math.sqrt(a)
assignment
<<
for

26. Function to empty the contents of a file - no recovery is possible
math.sqrt(a)
while

n

28. divide AND assignment operator
^
input()
/=
round()

29. Greater than or equal symbol.

>=

30. Greater than symbol
>
argument variable
/=
Variables

31. floor division AND assignment operator
print()

32. 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
else
floating point number
>>
%s

33. unction to read one line of a file
for
>>
%s
readline

34. Greater than or equal symbol.

^
del
if
*readline

38. Where the parameters go. A necessary punctuation after any function even if it's empty.
*truncate
%d
+
()

39. deletes an item from a list
