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 keyword that does nothing but fill space to indicate code which will be written later.
=
pass
class
str()

2. A built-in function that converts integers and strings to floating-point numbers.
+=
float
Variables
file.readline()

3. 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
str
a**b
Variables
^

4. This keyword in the body of a conditional allows chained conditionals.
#
elif (Else if)
a**b
def

5. Prints a string to the screen which is converted using repr()
a**b
>
%r
-

6. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
truncate
%r
def
&

7. Less than symbol
%r
file.readline()
<
not in

8. adds an item to a list
n
*read
|
append()

9. deletes an item from a list
raise
del
Variables
not in

10. Symbol used to create comments
floating point number
%s
==
#

11. subtract AND assignment operator
int
class
%=
-=

12. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
del
truncate
open()
|

13. Adds a new line character
break
n
a**b
*write(stuff)

14. absolute value
()
abs(a)
math.sqrt(a)
**=

15. turns an object into an integer
int()
>>
a**b
not

16. returns the length of a string (number of characters)
a**b
len()
<
()

17. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
>>
n
~
#

18. unction to read one line of a file
not in
readline
del
&

19. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
>=
read
&
Variables

20. 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.
print()
#
=
not in

21. Function to write something to a file
//=
<=
write
>>

22. square root
>=
math.sqrt(a)
<
break

23. floor division AND assignment operator
insert()
//=
else
a**b

24. 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).
else
is not
append()
==

25. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
<<
file.write(stuff)
%d
|

26. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
continue
-=
else
and

27. rounds a number to the number of decimal points you choose
for
%
:
round()

28. End header line.
//=
#
:
+=

29. exponent AND assignment operator
except
:
&
**=

30. A logical operator which negates an expression so that it returns a value of True if the expression is false.
not
is not
*readline
int()

31. empties the file
/=
print
%=
file.truncate()

32. writes stuff to the file
and
argv
append()
file.write(stuff)

33. The keyword beginning a header that will create a new function.
def
*=
class
*

34. inserts an item inside a list at a certain index
#
%d
insert()
a%b

35. Adds something to a variable
^
def
n
=

36. Function to close a file - it will not be able to be used again unless the file is opened.
close
