Possible test question types
Oct 4, 2011
CSE 1310-004 (Tiernan)

Below are examples of the kinds of questions I might ask on an exam. Try
to work through these and then we can discuss your answers on Thursday
in class if desired. I will not do a review for the test so your
questions on Thursday will be your opportunity to find out about the
test or to explore what I am looking for in regard to these questions.

A. Given the Python code below , indicate all syntax errors. Number each
location that has an error. After the code, list your numbers and
describe what the error is and what should be done.

Def uber(wald) #no colon; should be "def" no 'D'
    print "Today is a good day"; # no ;
    while k < 10:  # k is undefined at this point
       wald = wald + k
       print "wald is " wald # need comma before variable wald
    m == wald # m is undefined because there is no assignment
		    # or comparison isn't saved or used
    if m % 2 == 0:
       return "even"
    else:
       return odd # odd is an undefined variable or
				# return "odd" to match other return




B. Describe in your own words what indentation 
is used for in Python.



C. Describe in your own words what a function 
is in Python, how it is
different from a plain program, and why you 
would use functions.






D. Given the code below describe in words what 
the function does in the
simplest terms.

def ankh( gaspode, gavin):      # a(3,8)  t=0
    temp = 0	             #test   gs =3, gv =8,   t 
    while gaspode > 0 :     # T      3      8      0
       temp = gavin + temp   # T      2     8       8
	  gaspode -= 1          # T      1      8       16
    return temp              # F      0      8       24


The function ankh returns the product of gaspode and gavin


D.a. If the input to function ankh above is 8 and 3, 
what is returned by ankh?

24

E. Write a Python program to read in value from the user 
indicating the
user's height and weight. Use the following algorithm 
to determine if
the person is slender, average, or muscled and tell 
the user which
applies to them. The algorithm is:


    BMI = weight in kg divided by the square of height 
		in meters
    An average BMI is roughly 21 - 24. Less than this i
s slender,
greater than this is muscled for purposes of this question.








F. What kind of error checking should be done if the 
input should be a
word with only alphabetic characters in it? Either describe in 
words or write a few
Python statements that would do the error check.

<notes: test for type string; check each character is a letter

Check to make sure input is a string,
if it is, check to make sure that every character in the 
string is a letter of the alphabet either lower or upper case


Ex: string with non-alphabetic chars moo = "cow16_moo"
if type(moo) == str:
	check = True
else:
	check = False

for ch in moo:
	if check == True:
		if ch in ['a':'z'] or ch in ['A':'Z'] or ch == 'z' or ch == 'Z':
			check = True
		else:
			check = False
if check == True:
	print "whoopee"
else:
	print "oops"




G. Give at least four values that should be used as 
input to test
function uber? What useful information would you 
get from testing these
values?
