how to declare array of class instances

[kiran.k]

hi everyone :-)

1>
	Could anyone tell me howto declare an array (or list) of class
	instances.
	
	say--
	
	class trial():
		tmp=0
		def func(self,x):
			self.tmp=x
			:
			
	inst=trial()   #instance of trial class
	arr=[]
	arr.append(inst) 
	
	however, all instances of trial as arr[0-n] seem to have the same
	values of local variables in the class.		
	i.e arr[0].tmp==arr[n].tmp
	
	even if the input from keyboard is taken as 
	for loop:
		arr[n].func( input(""))
		
	arr[0].tmp would hold the last value inputted in the for loop
	i.e that of arr[n].tmp
	
2>     	suppose a function takes three parameters
	def func(self,x,y,z):
		--
		
	if i want the parameters to be keyboard inputs,
	is there any other way besides
	
	func( input(""), input(""), input(""))
	
	thanking you in anticipation
