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. Function to open or read a file
str()
/=
open()
len()

%d
()
+

6. add AND assignment operator
%s
print()
+=
close

7. Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. a << 2 will give 240 which is 1111 0000
<<
is not
str

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

9. absolute value
&
abs(a)
~
file.readline()

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
insert()

^
~

13. Command to print to the screen
#
*=
%=
print

14. Symbol used to create comments

print
abs(a)
close
continue

17. assignment operator

=
elif (Else if)
~

18. 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.
