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. Function to empty the contents of a file - no recovery is possible
a**b
write
class
truncate

2. This keyword begins a header for a body that repeats until the condition is no longer true.
while
not
input()

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

4. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
*=
//=
read
and

5. A logical operator which returns a value of True if either of the conditions is true.
abs(a)
or
==
^

6. empties the file
readline
not in
+
file.truncate()

7. ,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.

assignment
pass
~

8. prints its parameter to the console
=
/
print()
%d

9. A keyword that does nothing but fill space to indicate code which will be written later.
in
*truncate
pass
input()

10. assignment operator
pass
=

and

11. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
<=
.py
&
/

12. Where the parameters go. A necessary punctuation after any function even if it's empty.
<
/=
()
else

13. Symbol to multiply things
#
print
*=
*

14. turns an object into an integer
//=
def
int()
=

15. subtract AND assignment operator
argument variable
-=
=
insert()

16. Function to read the contents of a file
append()

not in
read

17. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
for
floating point number
n
|

18. Function to open or read a file
open()
or
+
argv

19. Writes stuff to the file.
=
file.readline()
*write(stuff)
int

20. Less than or equal to symbol
<
<=
write
read

21. Symbol to multiply things
*
^
print
+=

22. reads just one line of a text file & keeps track of where in the file you're at
**=
>
input()
file.readline()

23. 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.
write
+=
not in
print

24. absolute value
>>
a%b
abs(a)
**=

25. This keyword begins the simplest form of a conditional statement.
abs(a)
insert()
del
if

26. A statement that displays a value on the screen.
&
print
readline
def

27. prints its parameter to the console
print()
del
assignment
len()

28. 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.
class
argument variable
not
>>

29. unction to read one line of a file
<=
floating point number
*write(stuff)
readline

30. The keyword beginning a header that will create a new function.
|
def
*read
and

31. Less than symbol
n
>=
-=
<

32. Function to close a file - it will not be able to be used again unless the file is opened.
+=
a//b
close
and

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

34. The keyword beginning a header that will create a loop.
abs(a)
print
append()
for

35. asks the user for a response and returns that response
float
write
input()
=

36. Symbol to subtract things from each other
if
try
=
-

37. 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
=
^
round()
<<

38. 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
try
>>
truncate
%

39. Empties the file - watch out if you care about the file.
*read
Variables
file.truncate()
*truncate

40. multiply AND assignment operator
if
+
*=
file.write(stuff)

41. subtract AND assignment operator
