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.
str()
elif (Else if)
not in
*write(stuff)

2. turns an object into an integer
<<
#
open()
int()

3. 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
&
print

4. absolute value
close
file.truncate()
*=
abs(a)

5. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
try
def
int()
a%b

6. modulo
raise
a%b
*
>>

7. Where the parameters go. A necessary punctuation after any function even if it's empty.
=
del
()
return

8. Prints a string to the screen which is converted using repr()
except
%r
~
len()

9. exponent AND assignment operator
input()
#
float
**=

10. turns an object into a string
del
insert()
str()
=

11. floor division
/=
readline
round()
a//b

12. This keyword begins a header for a body that repeats until the condition is no longer true.
.py
==
print()
while

13. Symbol used to create comments
write
truncate
#
a//b

14. deletes an item from a list
del

append()
def

15. square root
>>
math.sqrt(a)
#
close

16. Less than symbol
**=
<=
if
<

17. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
input()
readline
format string
n

18. Greater than symbol
format string
-
>
str()

19. Function to open or read a file
file.write(stuff)
open()

a**b

20. square root
math.sqrt(a)
is not
()
for

21. Prints a string to the screen which is a signed decimal.
%d
>=
input()
read

22. returns the length of a string (number of characters)
except
%s
insert()
len()

23. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
append()
insert()
is
class

24. An operator to check whether two variables refer to the same object.
Variables
is
argv
-

25. A statement that displays a value on the screen.
input()
print
=
file.readline()

26. unction to read one line of a file

27. rounds a number to the number of decimal points you choose
Variables
del
round()
a**b

28. A logical operator which compares two operands and produces True if they are equal and False otherwise
int
+=
else
==

29. modulus AND assignment operator
%=
floating point number
str
math.sqrt(a)

30. add AND assignment operator
print
and
+=
raise

31. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
round()
not
Variables
int()

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
>>
floating point number
try
int

33. Symbol to add things together
~
*
+
>

34. 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
^
round()
