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.

8. This keyword in the body of a conditional - gives an alternative execution.
<=
del
else
and

9. assignment operator
<

10. 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
print
argument variable
>
>>

11. A data type for representing numbers with fractional values.
floating point number
*readline
#
%d

12. modulo
a%b

and
n
return

14. Turns a line into a comment instead of executable code.

&
*truncate
.py

19. returns the length of a string (number of characters)

#

20. The keyword beginning a header that will create a new function.
%=
def
open()

for
Variables

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

%r
=

24. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
&
<<
format string
/

25. 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

class
int()
write

32. Greater than or equal symbol.
