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. exponentiation
>=
float
%d
a**b

2. The keyword beginning a header that will create a new function.
#
<
int
def

3. 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
<<
len()
#
print()

4. A logical operator which requires two expressions to both be true.
**=
+
for
and

5. This keyword begins the simplest form of a conditional statement.
if
argv
=
.py

6. Prints a string to the screen which is a signed decimal.
%r
%d
<=
break

7. divide AND assignment operator
/=
write
%
for

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

9. Create a variable.
truncate
format string
=
%r

10. add AND assignment operator
|
+=
in
readline

11. This keyword begins the simplest form of a conditional statement.
round()
if
*write(stuff)
file.truncate()

12. Symbol to divide by the number to the right of the symbol
float
math.sqrt(a)
/
round()

13. subtract AND assignment operator
%r
write
-=
file.truncate()

14. 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

<<
break
*

15. Function to read the contents of a file
in
%=
read
floating point number

16. 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.
input()
in
assignment
**=

17. Where the parameters go. A necessary punctuation after any function even if it's empty.
print
/=
()
a%b

18. Adds a new line character
float
%=
a**b
n

19. Symbol to subtract things from each other
<
-
%s
%

20. Function to open or read a file
/
open()
read
+=

21. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
except
|
file.write(stuff)
%

22. Symbol to multiply things
*
+=
file.readline()
#

23. A keyword that does nothing but fill space to indicate code which will be written later.
pass
.py
append()
%

24. End header line.
#
<<
float
:

25. Prints a string to the screen which is a signed decimal.
=
else
%d
a//b

26. returns the length of a string (number of characters)
/
*=
append()
len()

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.
floating point number
%r
not in
len()

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

29. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
try
Variables
class
%d

30. The extension for Python scripts
.py
>=
print()
if

31. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
a//b
//=
Variables
>

32. End header line.
:
%s
close
len()

33. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
