this is a weird request, but i'm weird too so it's alright...

[inkedmn]

i need ideas for things i can code to practice python. i'm as NEWBIE as the day is long, so try to keep them basic (even TOO basic would be fine, just so i can feel like i'm doing things)...

TLD - this is just for the times when i'm stuck and you're actually doing what you get paid to do instead of helping my sorry butt :).

thanks all

and TLD is rad for all the help he's giving me...

Go to http://darkhost.mine.nu:81 and grab my Ruby example. They are commented. Try to translate them to Python. Most of them are very simple.

Hah, I just did a rock/paper/scissors game in python yesterday. The computer always wins. :D

post it!

a = 0
b = 0
def lose():
print "Sorry, but you lose."
while a == 0:
c = raw_input("Do you want (r)ock, (p)aper, or (s)cissors? ")
if c == "r" or c == "R" or c == "p" or c == "P" or c == "s" or c == "S":
if c == "r" or c == "R":
print "Paper covers rock."
lose()
a = 1
elif c == "p" or c == "P":
print "Scissors cuts paper."
lose()
a = 1
else:
print "Rock crushes scissors."
lose()
a = 1
else:
print "What?"

There is probably a way to make the script shorter, but I couldn't figure anything out.

Why doesn't....

if c == "r" or "R" or "p" or "P" "s" or "S":

.....work for line 7?

I was thinking of using my R/P/S game and try to make the computer actually have to "think" about which move is best, rather than me telling it which is. I don't know how to go about doing it, but I figured this might be the format:
# 1st: The player types in his message.

Input text....
Player said: rock

# 2nd Computer will be given the rules of the game:

ROCK
can be COVERed
can CRUSH
PAPER
can be CUT
can COVER
SCISSOR
can be CRUSHED
can CUT
BEING CRUSHED, CUT, or COVERED is bad!

# 3rd computer makes a random guess,
# then it sees if the guess will make it win.

Computer guesses: SCISSORS.
computer thinks:
SCISSORS can be CRUSHED by the user's ROCKS
== bad!

# 4th if choice was bad! then the computer
# trys another random guess (minus the guess
# it just made) until it makes a good option.
Is this weird enough for you?

because between your "P" and "s" there is no or... ;)

Do a calculator that has more than just your regular simple functions.

You could build a small database using shelve that stores your cd/mp3/dvd or whatever collection then writes it to a file in a formatted way.

You could write a small email client for yourself that checks your pop3 accounts..(this is MUCH easier than it sounds), you could even learn threads this way by allowing you to write an email while it still checks it at a fixed time like every 5 minutes or so. This would also be a good way to teach you the time library, it kinda threw me for a loop when I first used it.

If I was going to recommend any of them to teach you some GREAT fundamentals of Python I would recommend the the email program. It can allow for learning file access, database access(if you so choose), time library, regular expressions as you have to parse the header of each email, threads(if you so choose). It can be a fun program to write, I should know that is what I did for my second program! ;)
