Problem 1:

27/15, int, 1
32%11, int, 10
sum(range(6)), int, 15
len("dog") < len("catsup"), boolean, true
"1,234,567".split(",") list, ["1", "234", "567"]
"platform"[-2], string, "r"
"beat"+"nick", string, "beatnick"
"snapdragon"[3:8] string, "pdrag"
0.23*10, float 2.3
[8,7,6,7,6,5,4,3,2,1][5:7] list [5,4]
2**4 int 16

Part B:

def rorhrer(weight,height):
    return 1.0*wieght*2768/(height**3)

def triangle_area(a,b,c):
    s = (a+b+c)/2.0
    area = math.sqrt(s*(s-a)*(s-b)*(s-c))
    return area

def divisor_sum(n):
    return sum([k for k in range(1,n) if n % k == 0])

or
    s = 0
    for k in range(n):
        if n % k == 0:
            s = s + k
    return s

def is_amicable(x,y):
    return divisor_sum(x) == y and divisor_sum(y) == x

def nearby(city,clist,apart):
    ret = []
    for elt in clist:
         if distance(elt[1],elt[2],city[1],city[2]) <= apart:
             ret.append(elt[0])
    return ret

Problem 3

Part A

The one test that doesn't pass is the third, when "big" is b then
the expression 

b in ["bad","news", "is", "trouble"]

evaluates to true so "clean" is returned, the word "bad" is never
checked.

Move the else: outside the loop, e.g.,

def censored(bad,headline):
    words = headline.split()
    for b in bad:
        if b in bad:
            return "censored"
    return "clean"

******
Part C:

index+2 skips the comma and space to get the first name
the slice uses index to get everything up to and NOT including the comma


Part D:

.find() returns -1 when the string isn't found, so -1+2 = 1 and the
slice gets "ob jones". The value of the slice "bob jones"[:-1] is
everything upto and not include the last character or "bob jone"

******
Problem 4

'dog', no ie and no ei found

line 8 since eii isn't 0 and 'c' occurs before the 'ei'

line 6 for similar reasons

Part B:

control falls through to the end since all the if expressions are false
so False is returned as no other return statements execute

Part C:

Start code with:

if iei == 0: return False
if eii == 0: return True
