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. Less than symbol
<
%
~
-=

2. Command to print to the screen
file.write(stuff)
write
print
len()

3. Function to open or read a file
()
n
argv
open()

4. This statement exits a function. The remaining lines of the function are not executed.
<<
return
&
%

5. A built-in function that converts its argument to a string.
str

:
*

6. Symbol used to create comments
and
#
truncate
del

7. Function to read the contents of a file
math.sqrt(a)
print
read
argv

8. Adds something to a variable
abs(a)
for
=
len()

9. The keyword beginning a header that will create a new function.
^
def
in
%d

10. Less than or equal to symbol
<=
try
^
=

11. A keyword that does nothing but fill space to indicate code which will be written later.
pass
>=
and
&

12. sets the file's current position
print()
<<
str()
file.seek()

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

14. A logical operator which compares two operands and produces True if they are equal and False otherwise
not
is
|
==

15. Function to empty the contents of a file - no recovery is possible
input()
truncate
print()
return

16. A statement that displays a value on the screen.
Variables
len()
round()
print

17. 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).
#
and
is not
for

18. This keyword in the body of a conditional - gives an alternative execution.
#
else
raise
*read

19. A logical operator which requires two expressions to both be true.
and
int
<<
Variables

20. single line comment
#
if
open()
-

21. Symbol to add things together
:
abs(a)
*write(stuff)
+

22. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
<=
n
*=
class

23. A logical operator which compares two operands and produces True if they are equal and False otherwise
==
argv
%
#

24. square root
not in
len()
math.sqrt(a)
=

25. add AND assignment operator
+=
%
write
%s

26. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
~
append()
floating point number
&

27. A statement that ends the current iteration of a loop but continues looping.
else
>>
continue
**=

28. floor division
a//b
%r
in
+=

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

30. inserts an item inside a list at a certain index
=
str()
while
insert()

31. Writes stuff to the file.
=
:
float
*write(stuff)

32. A logical operator which negates an expression so that it returns a value of True if the expression is false.
not
del
len()
del

33. 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
del
^
file.seek()
a%b

34. This keyword begins the simplest form of a conditional statement.
open()
if
|
:

40. Prints a string to the screen which is converted using repr()
%=
&
str()
%r

41. reads just one line of a text file & keeps track of where in the file you're at
~
file.readline()
()
file.seek()

42. turns an object into a string
str()
<=
>
/=

43. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
try
read
break
/=

44. Greater than symbol
