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. This keyword in the body of a conditional - gives an alternative execution.
math.sqrt(a)
def
else
a**b

2. returns the length of a string (number of characters)
len()
#
=
^

3. A logical operator which compares two operands and produces True if they are equal and False otherwise
*readline
>=
==
<=

4. Argument variable
>=
argv
%
+=

5. Adds something to a variable
a//b
/
=
del

6. Where the parameters go. A necessary punctuation after any function even if it's empty.
()
>
//=
%r

7. Function to read the contents of a file
#
%
+
read

8. 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
a//b
&
>=

9. asks the user for a response and returns that response
>
argv
input()
abs(a)

10. Symbol used to create comments
>
abs(a)
#
^

11. square root
**=
math.sqrt(a)
%=
a//b

12. An operator that removes a value from a list.
open()
n
abs(a)
del

13. Function to empty the contents of a file - no recovery is possible
=
def
<<
truncate

14. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
print
a%b
write
and

15. Modulus operator. It's the remainder after division
abs(a)
raise
==
%

16. single line comment
*=
#
Variables
float

17. inserts an item inside a list at a certain index
insert()
*readline

and

18. Symbol to add things together
()
n
+
~

19. A built-in function that converts integers and strings to floating-point numbers.
file.seek()
*=
float
else

20. modulus AND assignment operator
int
file.seek()
%=
truncate

21. Function to empty the contents of a file - no recovery is possible
format string
and
truncate
print

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

23. Prints a string to the screen which is a signed decimal.
=
append()
%d
open()

24. Where the parameters go. A necessary punctuation after any function even if it's empty.
def
()
a//b
input()

25. divide AND assignment operator
del
/=
round()
%d

26. absolute value
abs(a)
else
open()
break

27. Symbol to multiply things
if
*
%r
/

28. This keyword begins a header for a body that repeats until the condition is no longer true.
int
while
str()
a**b

29. The extension for Python scripts
else
*=
.py
-

30. Symbol to divide by the number to the right of the symbol
str()
**=
insert()
/

31. modulo
-=
a//b
a%b
abs(a)

32. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
>
close
abs(a)
try

33. Reads the contents of the file you can assign the result to a variable.
*read
not in
except
print

34. modulus AND assignment operator
=
=
assignment
%=

35. A built-in function that converts its argument to a string.
if
/=
and
str

36. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
file.truncate()
class
~
def

37. Argument variable
format string
argv
%d
%r

38. empties the file
//=
<=
a%b
file.truncate()

39. 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
<<

.py
-

40. rounds a number to the number of decimal points you choose
round()
=
file.truncate()
or

41. 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
elif (Else if)
-=
=
^

42. A logical operator which compares two operands and produces True if they are equal and False otherwise
==
not in
in
a//b

43. This keyword in the body of a conditional - gives an alternative execution.
and
&
else
open()

44. This keyword begins the simplest form of a conditional statement.
if
%s
.py
str()

45. ,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.
argv
&
def

46. Turns a line into a comment instead of executable code.
#
def
print()
else

47. A statement that breaks out of a loop.
-
break
^
pass

int
>=
write
readline

49. End header line.
read
round()
:
*

50. Reads just one line of a text file.
argument variable
