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. rounds a number to the number of decimal points you choose
str()
+
round()
break

2. This keyword begins the simplest form of a conditional statement.
if
a**b
/
**=

3. unction to read one line of a file
readline
Variables
and
<

4. 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()
input()
a**b
>>

5. Prints a string to the screen which is converted using repr()
a**b
%r
==
input()

6. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
int
if
str()
%r

7. Less than symbol
str()
print
<=
<

8. Function to open or read a file
+=
open()
close
**=

9. asks the user for a response and returns that response
def
input()
%r
pass

10. This keyword begins a header for a body that repeats until the condition is no longer true.
floating point number
continue
float
while

11. This statement causes an exception.
print
raise
Variables
a%b

12. 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).
continue
is not
:
except

13. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
file.readline()
is not
~
len()

14. The extension for Python scripts
.py
or
+
floating point number

15. Prevents a runtime error from stopping the program.
argument variable
and
except
=

16. Turns a line into a comment instead of executable code.
input()
#
()
*read

17. Function to empty the contents of a file - no recovery is possible
insert()
//=
round()
truncate

18. Prints a string to the screen which is converted using repr()
argv
or
%r
truncate

19. Greater than symbol
>
-
append()
-=

20. The keyword beginning a header that will create a new function.
def
==
>=
*readline

21. Create a variable.
elif (Else if)
<=
input()
=

22. Greater than or equal symbol.
math.sqrt(a)
>=
del
**=

23. turns an object into an integer
floating point number
int()
in
%d

24. This keyword in the body of a conditional - gives an alternative execution.
()
else
read
>=

25. Function to close a file - it will not be able to be used again unless the file is opened.
try
*=
file.truncate()
close

26. Adds something to a variable
-
>
=
/

27. 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
close
else

28. The keyword beginning a header that will create a loop.
^
.py
file.readline()
for

29. floor division AND assignment operator
//=
#
not
return

30. A built-in function that converts its argument to a string.
str
insert()
*
pass

31. multiply AND assignment operator
*=
=
str()

*
insert()
del

33. subtract AND assignment operator
for
-=
+
del

34. 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
elif (Else if)
<<

a**b

35. absolute value
abs(a)
