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. Prints a string to the screen which will be Unicode.
def
except
%s
==

2. 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
%
/=
<<
argv

3. Adds something to a variable
=
%
open()
not in

4. Function to empty the contents of a file - no recovery is possible
-
//=
truncate
not

5. Turns a line into a comment instead of executable code.
%s
#
try
n

6. Prevents a runtime error from stopping the program.
~
%d
close
except

7. This keyword begins the simplest form of a conditional statement.
if
#
()
print()

8. This statement exits a function. The remaining lines of the function are not executed.
a%b
Variables
abs(a)
return

9. A logical operator which returns a value of True if either of the conditions is true.
or
>
try
break

10. floor division AND assignment operator
/=
//=
%s
del

11. sets the file's current position
%=
file.seek()
n
insert()

12. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
close
+
**=
~

13. exponent AND assignment operator
*=
&
floating point number
**=

14. Reads the contents of the file you can assign the result to a variable.
**=
*read
if
/

15. Function to write something to a file
append()
#
break
write

16. modulo
<=
class
#
a%b

17. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
if
print
.py
try

18. empties the file
continue
<<
file.truncate()
-

19. modulus AND assignment operator
%=
+
>
^

20. adds an item to a list
math.sqrt(a)
is not
abs(a)
append()

21. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
a%b
+
str()
Variables

22. Reads just one line of a text file.
close
=
*readline
|

23. 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).
*=
file.write(stuff)
is not
%s

24. Symbol to divide by the number to the right of the symbol
/
Variables
int()
==

25. unction to read one line of a file
<
=
readline
:

26. deletes an item from a list
truncate
float
del
-=

27. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
&
%s
append()
del

28. Function to read the contents of a file
def
and
<
read

29. floor division AND assignment operator
abs(a)
//=
*
%

30. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
raise
&
>=
abs(a)

31. multiply AND assignment operator
readline
*=
*truncate
^

32. A statement that assigns a value to a variable.
#
assignment
<<
//=

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
=
print
^
&

34. square root
=
math.sqrt(a)
*=
not in

35. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.
in

==
a//b

36. A built-in function that converts its argument to a string.
~
%r
str

38. Prints a string to the screen which is converted using repr()
while
=
%=
%r

39. divide AND assignment operator
round()
>>
%s
/=

40. This keyword in the body of a conditional - gives an alternative execution.
#
~
else
is

41. Greater than symbol
if
print
abs(a)
>

42. 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.
