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. Empties the file - watch out if you care about the file.
a**b
-=
*read
*truncate

2. exponentiation
**=
a**b
<
int()

3. ,multi-line comment hard-code,Fix (data or parameters) in a program in such a way that they cannot easily be altered by the user.

*write(stuff)
<=

4. modulus AND assignment operator
read
*readline
%=
-

5. A logical operator which requires two expressions to both be true.
and
is
close
class

6. writes stuff to the file
int()
file.write(stuff)
*=
+

7. square root
math.sqrt(a)
%s
%
*truncate

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

9. subtract AND assignment operator
-=
math.sqrt(a)
<
insert()

10. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
except
+
/=
|

11. assignment operator
else
format string
floating point number
=

12. 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.
not in
read
/=
a**b

13. rounds a number to the number of decimal points you choose
round()
len()

str()

14. Prints a string to the screen which is a signed decimal.
<
print
>
%d

15. multiply AND assignment operator
try
*=
/=
=

16. Adds a new line character
break
assignment
()
n

17. A logical operator which negates an expression so that it returns a value of True if the expression is false.
for
not
read
>=

18. 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.
math.sqrt(a)
continue
in
+=

19. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.
in
>=
floating point number
int()

20. Greater than symbol
>>
>
write
^

21. End header line.

argv
del
continue
str()

28. This statement causes an exception.
file.write(stuff)
file.readline()
/
raise

29. This keyword in the body of a conditional - gives an alternative execution.
readline

38. Adds something to a variable
=
def
/=
>

39. An operator to check whether two variables refer to the same object.
//=
abs(a)
is
