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

2. ,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.

%
%d
Variables

3. Turns a line into a comment instead of executable code.
<=
>
=
#

4. prints its parameter to the console
==
**=
+
print()

5. Less than symbol
while
#
a**b
<

6. single line comment
>>
input()
#
Variables

7. Adds a new line character
abs(a)
n
%s
in

8. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
int
-=
<=
else

9. Writes stuff to the file.
#
is
*write(stuff)
-

10. unction to read one line of a file
math.sqrt(a)
%
readline
raise

11. Prints a string to the screen which is a signed decimal.
readline
%r
%=
%d

12. turns an object into a string
math.sqrt(a)
n
%s
str()

13. rounds a number to the number of decimal points you choose
def
close
not in
round()

14. The keyword beginning a header that will create a loop.
open()
insert()
truncate
for

15. Empties the file - watch out if you care about the file.
insert()
*truncate
>
file.write(stuff)

16. A logical operator which requires two expressions to both be true.
insert()
and
readline
-

17. This keyword in the body of a conditional allows chained conditionals.
input()
math.sqrt(a)
=
elif (Else if)

18. floor division
=
argument variable
%
a//b

19. rounds a number to the number of decimal points you choose
round()
*=
if
a//b

20. subtract AND assignment operator
-=
input()
*
~

21. Prints a string to the screen which is converted using repr()
%r
/=
else
print()

22. The keyword beginning a header that will create a loop.
truncate
str()
<<
for

23. Command to print to the screen
:
n
print
()

24. exponent AND assignment operator
**=
if
file.readline()
abs(a)

25. A statement that ends the current iteration of a loop but continues looping.
try
readline
#
continue

26. square root
%r
*read
else
math.sqrt(a)

27. Greater than symbol
=
+
in
>

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

format string
%d
.py
readline

30. Function to write something to a file

def
**=
len()
a//b

34. Adds a new line character
<
a**b
n
round()

35. This statement exits a function. The remaining lines of the function are not executed.
print()
return

36. Reads the contents of the file you can assign the result to a variable.
==
*read
and

37. This variable holds the arguments you pass to your Python script when you run it. Then you unpack it in your script so you have variables you can work with.
