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. 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.

a**b
def
5. Prints a string to the screen which is converted using repr()

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

10. Symbol used to create comments
floating point number
%s
==
#
11. subtract AND assignment operator

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

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.
