A deposit and withdrawal programming(입/출금 프로그램)

• Object orientation 

def person_init(name, money):
	obj = {'name': name, 'money': money}
	obj['give_money'] = Person[1]
	obj['get_money'] = Person[2]
	obj['show'] = Person[3]
	return obj

def give_money(self, other, money):
	self['money'] -= money
	other['get_money'](other, money)

def get_money(self, money):
	self['money'] += money

def show(self):
	print('{} : {}'.format(self['name'], self['money']))

Person = person_init, give_money, get_money, show

if __name__ == "__main__":
	g = Person[0]('greg', 5000)
	j = Person[0]('john', 2000)
	
	g['show'](g)
	j['show'](j)
	print('')

	g['give_money'](g, j, 2000)
	
	g['show'](g)
	j['show'](j)

• Object orientation using class

class Person:
	def __init__(self, name, money):
		self.name = name
		self.money = money
	
	def give_money(self, other, money):
		self.money -= money
		other.get_money(money)
		
	def get_money(self, money):
		self.money += money
		
	def show(self):
		print('{} : {}'.format(self.name, self.money))
		
if __name__ == "__main__":
	g = Person('greg', 5000)
	j = Person('john', 2000)
	
	g.show()
	j.show()
	
	g.give_money(j, 2000)
	print('')
	
	g.show()
	j.show()

Can you see the difference?
