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

2. 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
def
math.sqrt(a)
+=
<<

3. inserts an item inside a list at a certain index
insert()
#
abs(a)
print

4. 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
a//b

5. Symbol to multiply things
^
>=
*
%s

6. Command to print to the screen
len()
print
truncate
+

7. exponentiation

str
a**b
^

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

9. rounds a number to the number of decimal points you choose
%=
len()
round()

<<
-=
else
insert()

11. assignment operator
and
=
str()
a%b

12. An operator to check whether two variables refer to the same object.
%d
argv
for
is

13. A logical operator which returns a value of True if either of the conditions is true.

truncate
~
or

14. An operator that removes a value from a list.
n
in
**=
del

15. The keyword beginning a header that will create a new function.

16. 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

21. reads just one line of a text file & keeps track of where in the file you're at
int()
~
file.readline()
is

22. 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
del
not in
close

23. The keyword beginning a header that will create a loop.
+
for

38. A logical operator which compares two operands and produces True if they are equal and False otherwise
readline
return
input()
==

39. 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).
==
%s
