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 built-in function that converts its argument to a string.
>>
str
readline
<

2. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
~
-
truncate
%s

3. Less than or equal to symbol
len()
close
del
<=

4. Writes stuff to the file.
*write(stuff)
break
&
<

5. divide AND assignment operator
/=
return
not in
**=

6. Greater than or equal symbol.
%s
not
>=
float

7. subtract AND assignment operator
>=
*readline
round()
-=

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

9. Function to write something to a file
<=
a%b
n
write

10. Function to empty the contents of a file - no recovery is possible
str()
-=
n
truncate

11. turns an object into a string
.py
str()
/
append()

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

13. 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
continue
print

14. A statement that ends the current iteration of a loop but continues looping.
del
-
continue
elif (Else if)

15. 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
while
<<
str()
abs(a)

16. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
abs(a)
format string
>>
append()

17. End header line.
:
return
==
#

18. inserts an item inside a list at a certain index
insert()
<<
argv
Variables

19. End header line.
:
is
insert()
truncate

20. An operator to check whether two variables refer to the same object.
abs(a)
is
**=
file.seek()

21. inserts an item inside a list at a certain index
=
insert()
pass
assignment

22. This statement causes an exception.
()
round()
%d
raise

23. Less than symbol
%d
a**b
file.truncate()
<

24. assignment operator
=
insert()
del
or

25. A logical operator which negates an expression so that it returns a value of True if the expression is false.
()
not
insert()
break

26. The keyword beginning a header that will create a loop.
for
input()
/=
==

27. Function to empty the contents of a file - no recovery is possible

file.write(stuff)
float
//=

28. Symbol to multiply things
^
Variables
is
*

29. Symbol to divide by the number to the right of the symbol
/
a//b
=
<

30. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
except
file.truncate()
/=
Variables

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

open()
truncate
file.seek()
#

37. Create a variable.
file.write(stuff)
def
Variables
=

print
=
read
-

39. Symbol to subtract things from each other
round()
()
-
:

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

43. Function to close a file - it will not be able to be used again unless the file is opened.
len()
close
%r
abs(a)

44. 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.
