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. 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
+=

2. empties the file
>
math.sqrt(a)
.py
file.truncate()

3. add AND assignment operator
+=
=
=
==

4. An operator that removes a value from a list.
print
.py
del
&

5. Adds a new line character
:
insert()
%r
n

6. 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
>>
read
*readline
read

7. This keyword in the body of a conditional - gives an alternative execution.
%
*=
else
a%b

8. Greater than or equal symbol.
while
argv
#
>=

9. Function to read the contents of a file
read
/
<<
=

10. absolute value
abs(a)
.py
print()
%=

11. This keyword begins a header for a body that repeats until the condition is no longer true.
while
>
**=
close

12. square root
.py
:
n
math.sqrt(a)

13. subtract AND assignment operator
-=
floating point number
n
=

14. exponentiation
append()
a**b
<=
print()

15. A keyword that does nothing but fill space to indicate code which will be written later.
*readline
pass
()
print

16. Greater than symbol
argv
else
%=
>

17. Adds something to a variable
=
if
*=
*=

18. 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.
**=
argument variable
close
n

19. The extension for Python scripts
>>
.py
#
<<

20. square root
~
math.sqrt(a)
()
not

21. Prints a string to the screen which is converted using repr()
**=
//=
%=
%r

22. Function to write something to a file
write
file.write(stuff)
+=
print

23. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
open()
~
a%b
try

24. 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
float
<<
n
file.write(stuff)

25. inserts an item inside a list at a certain index
file.seek()
#
insert()
close

26. Modulus operator. It's the remainder after division
%
len()
continue
while

27. asks the user for a response and returns that response
input()
>
file.truncate()
write

28. unction to read one line of a file
=
readline
in
math.sqrt(a)

29. exponentiation
math.sqrt(a)
write
a**b
except

30. Less than or equal to symbol
#
<=
>
=

31. ,multi-line comment hard-code,Fix (data or parameters) in a program in such a way that they cannot easily be altered by the user.
del

round()
*

32. prints its parameter to the console
elif (Else if)
print()
*=
>

33. Symbol used to create comments
-
input()
#
truncate

34. Symbol used to create comments
append()
class
#
/

35. modulus AND assignment operator
floating point number
%=
%d
if

36. Prints a string to the screen which will be Unicode.
file.truncate()
=
a**b
%s

37. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
else
try
*
open()

38. A data type for representing numbers with fractional values.
abs(a)
readline
:

39. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
|
*write(stuff)
n
del

40. returns the length of a string (number of characters)
len()
if
round()
+=

41. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
:
int
print
and

42. Prevents a runtime error from stopping the program.
