Hey, that seems like a good first try. Here are some points I'd pick up on first:
# Getting to know you
userName = raw_input("Hi, don't get too hasty, enter your name: ")
print "Hi there, " +name +" it's nice to meet you! Let's move on..."

# here is an example of a sentinal controlled iterator,
# which will save you writing out the same code over and over

counter = 0 # create an 'empty' variable
userPicks = [] # create a list to store the users lottery picks
while counter < 5:
# grab a number from the user, store it as an int
pickedNumber = int(raw_input("Please enter a number: "))
# append that to the list we created earlier
userPicks.append(pickedNumber)
# just to highlight the use of sentinal controlled values
print "The counter is currently " +str(counter)
# iterate the sentinal by 1
counter += 1
You can also use the same methods above, but generating another instance of random.randint() each time. You can then compare the contents of both lists, the easiest way to do this is to sort both lists - then compare them. to do this, you'll need to refer to the Python documentation (make use of the interpreter if you're struggling.)

thanks for the tips, and what does "+=" mean? I'd assume it's another syntax for >= ?

In Python, it will increment your value by one.

identical:

bla += 1 - 2
bla = bla + (1 - 2)

Try using this code:

#Simple Lotto program
import random
import time

picked = 0


#Greeting
print('''Hello! Welcome to Xog\'s Lotto Application. Thank you for taking the time to test my application out.
To play this Lotto game, I want you to pick three numbers from 1 through 5.''')

#Waits for 2 seconds.
time.sleep(2)

#Getting to know you
print('Don\'t get hasty! First, I want you to tell me your name. Please type it in and press Enter.')
name = raw_input()
print('Hello, ' + name + ', my name is Xog.')

#Number picking
number = random.randint(1, 5)
print('Okay, now that we know eachother a little bit, I think it\'s time we begin.')

while picked < 3:
print('Please pick a number from 1 through 5.')
playerPicked1 = raw_input()
playerPicked1 = int(playerPicked1)
picked = picked + 1

print('Pick your second number, between 1 and 5, that you did not pick.')
playerPicked2 = raw_input()
playerPicked2 = int(playerPicked2)
picked = picked + 1

print('Pick your third and last number, between 1 and 5, that you did not pick.')
playerPicked3 = raw_input()
playerPicked3 = int(playerPicked3)
picked = picked + 1

#Your issue was here. You can't do playerPicked1 or playerPicked2 or playerPicked3 == number.
if (playerPicked1 == number) or (playerPicked2 == number) or (playerPicked3 == number):
number = str(number)
print('The lotto number was ' + number + '! Congratulations! You\'ve just won $500 Hyperspace Dollars!')
time.sleep(3)
print('Well.. Okay, maybe not the money.')
else:
number = str(number)
print('Sorry, the last number was ' + number + '.')

print('Thanks for playing Xog\'s lotto!')

What I saw wrong was first of all, you used input(). Use raw_input(). input() expects a valid python expression for input. Also the reason why this wasn't working at all was you did

playerPicked1 or playerPicked2 or playerPicked3 == number. It should be (playerPicked1 == number) or (playerPicked2 == number) or (playerPicked3 == number). And instead of making

a new if statement you could have used an else.

Ahh, thank you! I was asking lynx and rootbear why the ors weren't working - they were both returning true no matter what. They didn't know the answer. Now I know. Thanks!

edit: tried to run your version and i get

Traceback (most recent call last):
File "C:/Documents and Settings/Administrator/Desktop/Python/lotto4.py", line 17, in
name = raw_input()
NameError: name 'raw_input' is not defined

so I changed all the raw_input() to input() and it works!

#Simple Lotto program
import random
import time

picked = 0


#Greeting
print('''Hello! Welcome to Xog\'s Lotto Application. Thank you for taking the time to test my application out.

name = input()
print('Hello, ' + name + ', my name is Xog.')

#Number picking
number = random.randint(1, 5)
print('Okay, now that we know eachother a little bit, I think it\'s time we begin.')

while picked < 3:
	print('Please pick a number from 1 through 5.')
	playerPicked1 = input()
	playerPicked1 = int(playerPicked1)
	picked = picked + 1
	
	print('Pick your second number, between 1 and 5, that you did not pick.')
	playerPicked2 = input()
	playerPicked2 = int(playerPicked2)
	picked = picked + 1
	
	print('Pick your third and last number, between 1 and 5, that you did not pick.')
	playerPicked3 = input()
	playerPicked3 = int(playerPicked3)
	picked = picked + 1

#Your issue was here. You can't do playerPicked1 or playerPicked2 or playerPicked3 == number.
if (playerPicked1 == number) or (playerPicked2 == number) or (playerPicked3 == number):
	number = str(number)
	print('The lotto number was ' + number + '! Congratulations! You\'ve just won $500 Hyperspace Dollars!')
	time.sleep(3)
	print('Well.. Okay, maybe not the money.')
else:
	number = str(number)
	print('Sorry, the last number was ' + number + '.')

print('Thanks for playing Xog\'s lotto!')

returns as:

Hello! Welcome to Xog's Lotto Application. Thank you for taking the time to test my application out.
To play this Lotto game, I want you to pick three numbers from 1 through 5.
Don't get hasty! First, I want you to tell me your name. Please type it in and press Enter.
Logan
Hello, Logan, my name is Xog.
Okay, now that we know eachother a little bit, I think it's time we begin.
Please pick a number from 1 through 5.
1
Pick your second number, between 1 and 5, that you did not pick.
2
Pick your third and last number, between 1 and 5, that you did not pick.
3
The lotto number was 3! Congratulations! You've just won $500 Hyperspace Dollars!
Well.. Okay, maybe not the money.
Thanks for playing Xog's lotto!

(possibly because I'm using python's GUI (IDLE)?)

As far as I know, input() asks the user to put any information in and stores it as the variable. the next line playerPicked1 = int(playerPicked1) turns the variable into an integer. Ofcourse, if the user put in something other than an integer it would result in an error but hey its just a simple little program and I'm still learning, so that's all I could do for now

Straight from python.org:

Warning

This function is not safe from user errors! It expects a valid Python expression as input; if the input is not syntactically valid, a SyntaxError will be raised. Other exceptions may be raised if there is an error during evaluation. (On the other hand, sometimes this is exactly what you need when writing a quick script for expert use.)

Consider using the raw_input() function for general input from users.

does that mean i'd have to def raw_input? if so how would that go?

edit: i also noticed that it might be because i'm using windows and not a unix platform:

Platforms: Unix

The readline module defines a number of functions to facilitate completion and reading/writing of history files from the Python interpreter. This module can be used directly or via the rlcompleter module. Settings made using this module affect the behaviour of both the interpreter’s interactive prompt and the prompts offered by the raw_input() and input() built-in functions.

i ordered a wireless PCI card for my PC from dealextreme.com to use ubuntu since my wireless USB adapter isn't supported and i couldn't find any working solution. I ordered it last month but it should be here by today or monday

It should be 'name = raw_input("What is your name?: ")'. If you leave the function empty, you'll get an error.

My bad on the use of multiple variables and operators to make a truth statement, 5am. :/

I've just done this a minute ago, I've not tested it so it probably won't run but:

# Bleuurghh bored, I should have gone to the pub...
import random
import time

def beginGame():
userName = raw_input("To begin, enter your name: ")
print("Hello, %s, my name is Xog." % userName)
randNumbers = []
userCoices = []
while len(userChoices) <= 4:
	randNumber = random.ranint(1, 5)
	randNumbers.append(randNumber)
	userChoice = int(raw_input("Pick a number between 1 and 5: ")
	userChoices.append(userChoice)
	print("So far you've picked: " +str(userChoices)
else:
	randNumbers.sort; userChoices.sort
	matchingNumbers = [i for i, j in zip(randNumbers, userChoices) if i == j]
	if len(matchingNumbers) > 0:
		print("Congratulations %s, you've won!" % userName)
		if len(matchingNumbers) == 4:
			print("You entered: " +str(userChoices) +" and our computer picked "\
			+str(randNumbers) +" and you managed to guess them all correctly! GJ!")
		elif len(matchingNumbers < 4:
			print("Unfortunately you never got them all correct, here are the ones\
			that you guessed: " +str(userChoices) +" and here are the ones that\
			our computer picked: " +str(randNumbers) +" better luck next time!")
			playAgain = str(raw_input("Would you like to play again? (y/n): ")
			if playAgain == y or playAgain == n:
				if playAgain == y:
					beginGame()
				elif playAgain == n:
					print("Thanks for playing!"); exit()
			else:
				print("Seeing as you can't hit y/n, you don't deserve me")
				exit()

print("Hello, welcome to Xog's Lotto application! Thank you for playing!.")
time.sleep(2)
beginGame()

That's an idea of how I'd do it.

Its optional to put the prompt in raw_input(). The script is working fine for me.

»Xog · February 7, 2010

It should be 'name = raw_input("What is your name?: ")'. If you leave the function empty, you'll get an error.

Traceback (most recent call last):

File "C:\Documents and Settings\Administrator\Desktop\Python\lotto4.py", line 16, in

name = raw_input('Don\'t get hasty! First, I want you to tell me your name: ')

NameError: name 'raw_input' is not defined

but yea screw that - cre> found what the problem was and the other one works fine with input(). lesson learned and back to the tutorial I go!

If I had gotten a chance to rewrite it in java, I probably would have figured it out.

Anywho, I overlooked that because, well, I was thinking the problem lied in the if part of the statement and the way you had it layed out.

I've had a chance to jump on Linux (where I have Python installed). Here is the correct code, it probably still has a couple of minor bugs but this is how I'd have done it:

# Lottery Application

playAgain = str(raw_input("Would you like to play again? (y/n): "))
if playAgain == 'y' or playAgain == 'n':
	if playAgain == 'y':
		userChoices = []
		randNumbers = []
		beginGame()
	elif playAgain == 'n':
		print("Thanks for playing!")
		exit()
	else:
		print("Let's try again, shall we?")
		playAgain()

def beginGame():
userName = raw_input("To begin, enter your name: ")
print("Hello, %s, my name is Xog." % userName)
randNumbers = []
userChoices = []
while len(userChoices) <= 4:
	randNumber = random.randint(0, 5)
	randNumbers.append(randNumber)
	userChoice = int(raw_input("Pick a number between 1 and 5: "))
	userChoices.append(userChoice)
	print("So far you've picked: " +str(userChoices))
else:
	randNumbers.sort(); userChoices.sort()
	matchingNumbers = [a for a in randNumbers if a in userChoices]
	if len(matchingNumbers) > 0:
		print("Congratulations " +userName +" you've won! You entered: " \
		+str(userChoices) +" and our computer picked " +str(randNumbers) \
		+" That's " +str(len(userChoices)) +" of " +str(len(randNumbers))\
		+" correct! Well done!")
	else:
		print "Sorry, you lost!"
		playAgain()

print("Hello, welcome to Xog's Lotto application! Thank you for playing!.")
time.sleep(2)
beginGame()

Yep, definitely has to do with me using windows. The only thing I changed in your code was the invalid syntax on line 39: print "Sorry, you lost!" to print("Sorry, you lost!")

Aiye, I've heard things about Python 3 that causes a lot of incompatibility; that could be why. Also, for future reference be careful with copy+pasting code from the web, as the code parser on this forum counts 1 tab as 8 spaces. There are usually functions on programming editors that allow you to convert spaces to tabs, which makes checking that kinda stuff quicker.

i know the point of this blog is python but hey...

Added class file incase you guys feel like testing it :excl:

if you dont know how to execute .class

Command Prompt (on windows, dont know how on other OSs)

navigate to folder you saved file in using the "cd" command

type: java Lotto

Lotto.class
