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. A logical operator which requires two expressions to both be true.
*=
return
int()
and

2. Function to open or read a file
while
open()
>
str()

3. adds an item to a list
=
+=
math.sqrt(a)
append()

4. This keyword begins the simplest form of a conditional statement.
if
#
argument variable
n

5. add AND assignment operator
+=
else
a**b
readline

6. 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
/
<<
==
^

7. Prints a string to the screen which will be Unicode.
continue
<
%s
n

8. Where the parameters go. A necessary punctuation after any function even if it's empty.
argv
()
%
int

9. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
#
and
print()
if

10. Symbol used to create comments
int()
#
<=
and

11. empties the file
file.truncate()
argv
len()
print

12. The extension for Python scripts
+
len()
a%b
.py

13. Reads the contents of the file you can assign the result to a variable.
>
=
*read
pass

14. modulo
()
and
a%b
&

15. unction to read one line of a file
argument variable
round()
del
readline

16. An operator that removes a value from a list.
del
>>
~
close

17. End header line.
int
write
|
:

18. Less than symbol
open()
<
/
/

19. exponentiation
-
a**b
argv
*readline

20. exponent AND assignment operator
=
**=
-
==

21. reads just one line of a text file & keeps track of where in the file you're at
file.readline()
truncate
/
file.truncate()

22. 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
>>
open()
|
open()

23. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
~
format string
&
input()

24. modulo
a%b
=
=
==

25. exponentiation
a**b
input()
%=
*=

26. This keyword begins the simplest form of a conditional statement.
()
write
or
if

27. A built-in function that converts its argument to a string.
str
append()
%
-=

28. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
*read
|
in
close

29. Greater than symbol
is not
file.write(stuff)
.py
>

30. Modulus operator. It's the remainder after division
//=
#
continue
%

31. The extension for Python scripts
-
.py
and
truncate

32. Reads just one line of a text file.
<<
except
*readline
a**b

33. Prints a string to the screen which will be Unicode.
+
file.seek()
input()
%s

34. 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
%s
file.write(stuff)
<=
^

35. sets the file's current position
>>
file.seek()
continue
+

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

37. Function to empty the contents of a file - no recovery is possible
#
:
truncate
/=

38. 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.
readline
not in
+=
in

39. turns an object into an integer
int()
a%b
str
%=

40. 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
#

41. Writes stuff to the file.
*write(stuff)
*truncate
break
str()

42. rounds a number to the number of decimal points you choose
+=
float
=
round()

43. This keyword in the body of a conditional allows chained conditionals.
==
+=
elif (Else if)
a**b

44. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
break
int
elif (Else if)
and

45. Less than or equal to symbol
<=
.py
not in
%s

46. The keyword beginning a header that will create a new function.
read
floating point number

48. This statement exits a function. The remaining lines of the function are not executed.
-=
truncate
=
return

49. floor division
=
a//b
not in
else

50. This variable holds the arguments you pass to your Python script when you run it. Then you unpack it in your script so you have variables you can work with.
