Selling just doesn't work!

Question

Okay, I am writing a dopewars clone/wannabe in python. I have it pretty much the way I want it, except that selling items does not work. Buying them does fine, it is just selling them.

Here is the code:

Any help would be greatly appreciated! I also attached the .py incase it is easier to test it without having to delete line numbers.

What doesn't work? Does it give you an error? Or does it just not function properly? what does it do?

snippsat 661 Master Poster

Sure you gone have big problems.
Global variables is a really bad thing,and you have used it a lot.

def la():
    clear()
    global cash, dealers, hp, gang

def foo_sell():
    global cash, dealers

Now cash,dealer is in global namespace.

global cash  #this is global namespace so no need to use global here.
cash = 500
global dealers
dealers = 2

Now do understand why this is a big mess?
This happen many times in your code an make global namespace a big mess off variables.
An important point with function is to keep data local to that function.
Not all variables get thrown out in global namespace.

I am not sure if someone can help you,without rewrite a lot off code.
You shold try to make normal function that takes argument and return data and remove all global.

forgot the .py... but it won't let me add it. sorry...

mruane 0 Junior Poster in Training · Answer 2 · 2009-12-13T05:42:37+00:00

It just doesn't do what it is supposed to.

It is supposed to function like this:

1. user chooses to sell an item
2. game removes item from inventory
3. game adds resulting cash to inventory.

here is the offending code:

def foo_sell():
	global cash, dealers
	clear()
	print """\
	
	Sell how many DEALERS?
	
	a. 1 dealer for $50
	b. 2 dealers for $100
	c. 3 dealers for $150
	
	or:
	
	d. exit
	"""
	x = raw_input("> ")
	if x == 'a':
		if dealers > 1:
			print "You sell 1 dealer  for $50."
			dealers = dealers - 1
			cash = cash + 50
			foo_sell()
		else:
			print "You do not have enough dealers to sell."
			print 'You have ', dealers, ' dealers to sell.'
			foo_sell()
	elif x == 'b':
		if dealers > 2:
			print 'You sell 2 dealers for $100.'
			dealers = dealers - 2
			cash = cash + 100
			foo_sell()
		else:
			print "You do not have enough to sell 2 dealers."
			print "You have ", dealers, " dealers to sell."
			foo_sell()
	elif x == 'c':
		if dealers > 3:
			print 'You sell 3 dealers for $150.'
			dealers = dealers - 3
			cash = cash + 150
			foo_sell()
		else:
			print 'You do not have enough to sell 3 dealers.'
			print 'You have ', dealers, ' dealers to sell.'
			bob_sell()

I have never had a problem with declaring globals like this before. I have tried and tried to come up with a fix, but, to no avail. which is why I came here, as a last resort. Does anybody have an idea of how to fix this?

woooee 814 Nearly a Posting Maven · Answer 4 · 2009-12-14T04:29:46+00:00

This program should use a class. For the foo_sell() function as it is, pass 'cash' and 'dealers' to it and return them as well, avoiding globals.

You have now and hopefully have learned that lesson.

Well, I took everyone's advice and used classes. It does work a lot better. I even added a gang war to the demo, but, your gang wins with one turn. I am including the code for the gangfight() function and all necessary classes so if anyone sees the problem, let me know so I can fix it.

# player class

class player():
	hp = 25
	cash = 500
	dealers = 2
	gang = 5
	guns = 0
	ganghp = 20

class hawksgang():
	ganghp = 25
	members = random.randrange(4, 10)

def gangfight():
	charhp = player.ganghp * player.gang
	thughp = hawksgang.ganghp * hawksgang.members
	print "The Hawks gang is attacking you!"
	print "Your gang: ", player.gang
	print "Hawks gang: ", hawksgang.members
	
	# player gang attacks
	
	chardmg = random.randrange(2) + 1
	attack = chardmg * player.gang
	print "Your gang attacks the Hawks!"
	print "You deal ", attack, "damage!"
	
	thughp -= attack
	print 
	print "Your gangs HP: ", charhp
	print "Hawks HP: ", thughp
	
	# hawks attack
	
	thugdmg = random.randrange(1) + 1
	attack = thugdmg * hawksgang.members
	print "The Hawks attack you!"
	print "They deal ", attack, "damage to your gang!"
	
	charhp -= attack
	print "Your gangs HP: ", charhp
	print "Hawks HP: ", thughp
	
	raw_input()
	if charhp < 1:
		print "The hawks have defeated your gang."
		print "Game Over."
		gameover()
	else:
		print "Your gang has defeated the Hawks!"
		cearn = random.randrange(10, 25)
		income = cearn * hawksgang.members
		print "You earned $", income ,"!\n"
		player.cash += income
		return

Now, I am a beginner, so let's try to keep to constructive criticism, not flaming for any errors or condescending for lack of organisation and the likes. I know it is not the best written code, but with some of the rewrites I will most likely be doing once I get it how I want it, it should be better. I learn by doing.

Selling just doesn't work!
