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

2. inserts an item inside a list at a certain index
or
insert()
Variables
/=

3. This keyword begins the simplest form of a conditional statement.
==
if
:
:

4. Function to empty the contents of a file - no recovery is possible
%=
argument variable
truncate
=

5. Prevents a runtime error from stopping the program.
read
*truncate
<
except

6. deletes an item from a list
-=
argument variable
del
|

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
//=
floating point number
^
<<

8. Adds something to a variable
append()
=
try
break

9. A logical operator which compares two operands and produces True if they are equal and False otherwise
math.sqrt(a)
-
%r
==

10. Greater than or equal symbol.
elif (Else if)
>=
**=
and

11. returns the length of a string (number of characters)
in
%d
len()
for

12. Reads the contents of the file you can assign the result to a variable.
a%b
%
>=
*read

13. A logical operator which returns a value of True if either of the conditions is true.
or
print
and
-=

14. Command to print to the screen
//=
print
file.truncate()
truncate

15. The keyword beginning a header that will create a new function.
a//b
%r
str()
def

16. Greater than symbol
()
>
else
read

17. unction to read one line of a file
readline
%d
n
()

18. A logical operator which negates an expression so that it returns a value of True if the expression is false.
open()
*write(stuff)
not
-=

19. returns the length of a string (number of characters)
*=
*=
len()
del

20. Argument variable
else
str
argv
file.readline()

21. Function to open or read a file
-
else
file.readline()
open()

22. assignment operator
del
assignment
while
=

23. 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
n
<<
except

24. Symbol to add things together
+
%s
%
<

25. Symbol to add things together
del
+
is

26. turns an object into a string
file.seek()
&
or
str()

27. Adds a new line character
a**b
/
n
=

28. empties the file
return
file.truncate()
and
raise

29. absolute value
abs(a)
>
truncate
+=

30. sets the file's current position
file.seek()
file.truncate()

int
int()
/=
%=

32. Turns a line into a comment instead of executable code.
n
%=
file.write(stuff)
#

33. Evaluates to false if the variables on either side of the operator point to the same object and true otherwise. x is not y - here is not results in 1 if id(x) is not equal to id(y).
format string
is not
#
*=

34. A built-in function that converts its argument to a string.
%s
str
input()
