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. returns the length of a string (number of characters)
len()
return
-
in

2. multiply AND assignment operator
=
&
*=
is not

3. Reads the contents of the file you can assign the result to a variable.
abs(a)
^
*read
argument variable

4. Symbol to subtract things from each other
if
math.sqrt(a)
-
round()

5. modulo
while
a%b
#
=

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

7. exponent AND assignment operator
file.truncate()
**=
=
<=

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
-
&
float
<=

9. Symbol to multiply things
~
int
*
is not

10. Adds something to a variable
return
=
Variables
for

11. Adds a new line character
^
math.sqrt(a)
/
n

12. This keyword begins the simplest form of a conditional statement.
>
open()
%s
if

13. ,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.

/
*truncate
#

14. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
truncate
Variables
format string
argv

15. adds an item to a list
argv
append()
:
pass

16. 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
>>
floating point number
<=
read

17. Prevents a runtime error from stopping the program.
<<
insert()
except
a%b

18. This keyword in the body of a conditional allows chained conditionals.
elif (Else if)
and
for
%d

19. Command to print to the screen
print
insert()
assignment

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.
=

not in
format string

21. Symbol used to create comments
read
open()
#
close

22. Less than or equal to symbol
%r
//=
>
<=

23. 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
>
close
a//b
^

24. 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
print
:

25. 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
^
