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
~

2. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.
del
in

and

3. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
+
class
continue
int

4. Where the parameters go. A necessary punctuation after any function even if it's empty.
n
read
math.sqrt(a)
()

5. absolute value
abs(a)
close
*
#

6. turns an object into an integer
%s
>>
int()
truncate

7. A keyword that does nothing but fill space to indicate code which will be written later.
pass

/
len()

8. Less than symbol
try
*
else
<

9. floor division

n
not
**=

10. The keyword beginning a header that will create a new function.
def
close
input()
^

11. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
file.seek()
format string
in
str()

12. A logical operator which requires two expressions to both be true.
truncate
^
write
and

13. A logical operator which negates an expression so that it returns a value of True if the expression is false.
def
not
del
in

14. Adds something to a variable
**=
*write(stuff)
=
&

15. Less than or equal to symbol
print
//=

16. Symbol used to create comments
=
if
/=
#

17. Greater than symbol

18. ,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.
+

Variables
+=

19. assignment operator
argv
del
=
if

20. adds an item to a list
#
=
input()
append()

21. This keyword begins a header for a body that repeats until the condition is no longer true.
while
and
Variables
%

22. This keyword in the body of a conditional - gives an alternative execution.
else
and

if

23. Turns a line into a comment instead of executable code.
+=
#
-
+=

24. divide AND assignment operator
argument variable
*
argv
/=

25. unction to read one line of a file
close
else
readline
>>

26. Function to close a file - it will not be able to be used again unless the file is opened.

input()
close
a//b

27. This statement causes an exception.
math.sqrt(a)
file.readline()
argv
raise

28. Function to empty the contents of a file - no recovery is possible
>
*readline
truncate
class

29. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.

%
input()

30. Function to open or read a file
continue
open()
=
read

31. Symbol to add things together

n
//=
%d
argv

34. Function to open or read a file
return
or
/=
open()

35. Function to close a file - it will not be able to be used again unless the file is opened.
close
math.sqrt(a)
read
%=

36. 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

38. Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. a >> 2 will give 15 which is 0000 1111
>>
argument variable
**=
append()

39. A statement that ends the current iteration of a loop but continues looping.
**=
readline
=
continue

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