[Beginner] Programming Challenge: 1

[nvteighen]

My first Python program! (Yes, believe me despite the dictionary with a tuple inside...)

Update: As I'm a C guy, I felt forced to refactor the code a bit and make it even more structured as I could!

#!/usr/bin/python

def choose(i):
    special = {0 : ("no more", "bottles"), 1 : ("1", "bottle")}
    if i not in special:
        modulo = (i, "bottles")
    else:
        modulo = special[i]
    return "%s %s" % modulo
    
b = 99
for i in range(b, -1, -1):
    print "%s of beer on the wall, %s of beer." % (choose(i).capitalize(), 
    choose(i))
    if i > 0:
        print "Take one down and pass it around,", choose(i - 1),
    else:
        print "Go to the store and buy some more,", choose(b),
    print "of beer on the wall.\n" 

[Reiger]

I like the Haskell version they have... a lot.

Thanks for the challenge. Here is what I got:

#!/usr/bin/python

beerCount = 99

while beerCount > -1:
    if beerCount == 0:
        print "No more bottles of beer on the wall.\n" "No more bottles of beer.\n" "Go to the store and buy some more, 99 bottles of beer on the wall.\n"
    elif beerCount == 1:
        print beerCount, "bottle of beer on the wall.\n", beerCount, "bottle of beer.\n", "Take one down, pass it around,", beerCount, "bottle of beer on the wall.\n"
    else:    
        print beerCount, "bottles of beer on the wall.\n", beerCount, "bottles of beer.\n", "Take one down, pass it around,", beerCount, "bottles of beer on the wall.\n"
    beerCount = beerCount - 1 

I took a a little formating advice from Reiger. I don't think I was missing any spaces, just capitalization and periods. Also, each verse did begin seperated by a blank line.

* You should decrement the beerCount before 'passing it around'

I don't understand what you mean here so I am just going to post my output:

[Reiger]

I'm not sure; as I don't know Python but intuitively I'd say your program has a few subtle 'formatting' issues?

* Missing spaces (but that could be my lack of Python, as I see others with the same thing?)
* Missing dots (.) at the end of a setence
* Missing comma's and newlines instead of comma's
* 'take' should be 'Take'
* You should decrement the beerCount before 'passing it around'
* Each verse is separated by a blank line

[Wybiral]

Generates the song line-by-line

def song(n):
    bob = lambda x: "%(x)s%(bottles)s of beer" % {
        "x": x if x > 0 else "no more",
        "bottles": "bottle" if x == 1 else "bottles"}
    otw = lambda x: "%(b)s on the wall, %(b)s." % dict(b=bob(x))
    tod = lambda x: "Take one down, pass it around, %s on the wall." % bob(x)
    for i in xrange(n, 0, -1):
        yield otw(i)
        yield tod(i - 1)

for line in song(99):
    print line

The end of the song is really actually really sad though...

@aktiwers : Please give your variables real names, a,b,c is not very descriptive ,exception : i as the default counter is a convention.

Edit : bugfix for a special case I missed.

Edit 2: Special cases are hard..

This was my 1st version and it didn't need any bugfixes , much more readable, but i guess it's against the spirit of the challenge.
