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. Less than or equal to symbol
argv
>
math.sqrt(a)
<=

2. empties the file
break
file.truncate()
=
file.readline()

3. adds an item to a list
read
append()
input()
.py

4. adds an item to a list
append()
.py
or
close

5. absolute value
else
abs(a)
except
%=

6. Less than symbol
<
return
*readline
del

7. modulus AND assignment operator
a**b
argument variable
%=
in

8. A built-in function that converts its argument to a string.
str
/=
del
**=

9. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
del
~
()
.py

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

11. 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).
and
elif (Else if)
is not
open()

12. The extension for Python scripts
str()
-
.py
+

13. sets the file's current position
while
-=
|
file.seek()

14. This keyword begins a header for a body that repeats until the condition is no longer true.
**=
else
#
while

15. Writes stuff to the file.
*write(stuff)
//=
<<
print()

16. A keyword that does nothing but fill space to indicate code which will be written later.
and
/=
pass
write

17. Argument variable
/=
argv
*=
>>

18. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
Variables
()
read
*truncate

19. A logical operator which requires two expressions to both be true.
is not
+
:
and

20. Adds a new line character
n
()
else
*

21. Command to print to the screen
-
print
>=
#

22. Greater than or equal symbol.
>=
and
#
input()

23. The keyword beginning a header that will create a new function.
%d
truncate
def
()

24. returns the length of a string (number of characters)
len()
file.truncate()
#
close

25. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
close
*write(stuff)
format string
/=

26. A data type for representing numbers with fractional values.
/=
insert()
()
floating point number

27. divide AND assignment operator
except
is not
/=
assignment

28. Prevents a runtime error from stopping the program.
del
except
open()
try

29. 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
>
str
open()
>>

30. subtract AND assignment operator
and
open()
len()
-=

31. Adds something to a variable
insert()
or
input()
=

32. Function to read the contents of a file
read
%d
=
+

33. turns an object into an integer
int()
str()
()
.py

34. Reads just one line of a text file.
*readline
>>
write
round()

35. 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
-
>>
a//b
=

36. inserts an item inside a list at a certain index

:
=
insert()

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

38. Turns a line into a comment instead of executable code.
del
#
Variables
print

39. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
class
len()
+=
==

40. Symbol to divide by the number to the right of the symbol
except
*
<<
/

41. Evaluates to true if it finds a variable in the specified sequence and false otherwise. x in y - here in results in a 1 if x is a member of sequence y.
a**b
del
in
a//b
