# Midterm Exam #2
# Review Sheet Hints and Code

# 1. There is a quick way to do this one that
#    doesn't involve a for loop.  Think back to
#    how the word[_:_] command works.


# 2. The following lines will come in handy at one point

if j not in randnums:
    count = count + 1


# 3. You can create the sides of the box (tabbed over) via

for letter in word:
    print"\t\t" + letter + " "*len(word) + letter


# 4. You'll need to build a new word for this one.  Use a for
#    loop such as

for letter in phrase:

#     and then use an if statement to check whether letter is
#     not equal to any of a,e,i,o,u.  (See the tip at the end
#     of the review sheet.)  If not, then add that letter
#     to the end of your word, and print it after the for loop.


# 5. I'll let you figure most of this out.  You'll want all the
#    action to take place within a while loop, and use the
#    values.append(number) command.


# 6. You will need a for loop such as

for j in range(0,len(string)-1):

#    Now count how many times the characters at positions j and j+1
#    are both vowels.  (See tip.)  Then use an if/else statement to wrap up.


# 7. This looks a lot like our database.py program.  Check there
#    for ideas if you need to.


# 8. Check back to our homework involving college rankings for ideas.


# 9. Try setting up a for loop such as

for j in range(0,len(roster)):
    
#    and check each entry for a match with the name.
#    Note that swapping two entries is trickier than
#    it looks!  You need to order your code carefully.
#    Also, to keep track of whether a match is made
#    define a variable appear = "no" and then change
#    appear to "yes" if you encounter a match.  Then
#    set up an if appear = "no": statement at the end.


# 10. Here's one way to code this one.

def parse(string):
    wordlist = []
    word = ""
    string = string + " "
    # we add a final space since we add words to the list
    # whenever we hit a space in the string
    for character in string:
        if character != " ":
            word = word + character
        else:
            wordlist.append(word)
            word = ""
    return wordlist


# 11. This is relatively straight-forward; I'll let you figure it out.


# 12. The following lines of code will come in handy.

for letter in string:
    if letter == " ":
        space = space + 1
    elif letter in vowels:
        # etc. etc.
