	[http://ascendbugs.cheme.cmu.edu/view.php?id=459 Issue 459] demands a way to assign values to a range of array elements. ~~It is in fact true that~~ Python ~~can't address range of array elements~~. ~~This~~ is ~~not covered~~ by the ~~syntax~~ of ~~the language and supporting this feature would require~~ a ~~patch for Python language itself (not ASCEND).~~		[http://ascendbugs.cheme.cmu.edu/view.php?id=459 Issue 459] demands a way to assign values to a range of array elements. Python invokes <i>__setslice__</i> method when something like " a[1:4] = .. " is used. Thus this task can be accomplished by overriding the <b>__setslice__</b> method of a list object as follows :
	~~I propose an alternate way to assign values to a range of array elements.~~

	~~===1. Assigning a value to all elements of an array===~~
	<source lang="py">		<source lang="py">
	~~a = [5]*length;~~		class myList(list):
			def __setslice__(self, i, j, sequence):
			for x in range(i,j):
			self.__setitem__(x,sequence)

	</source>		</source>
	~~here <i>length</i> can be the length~~ of ~~array 'a' ie: len(a) if <b>a</b>~~ is ~~already initialized or it can be a numerical value if <b>a</b> is being initialized right now.~~		The use of this class is demonstrated as follows :
	~~<br />example~~:
	<source lang="py">		<source lang="py">
	~~>>>~~ a = ~~[2]*6~~;		a = myList('123456789');
	~~>>>~~ a		print a;
	~~[2,2,2,2,2,2]~~		a[1:4] = 5;
	~~</source>~~
	~~===2. Assigning a value to a partial range of elements of an array===~~
	~~<source lang="py">~~
	~~for i in range(0,5):~~
	a[~~i] =~~ 1;
	~~</source>~~
	~~This will produce the desired effect.~~
	~~<br />example~~:
	~~<source lang="py">~~
	~~a = [4]*10~~
	~~for i in range(0,~~4):
	~~a[i~~] = 5;
	print a;		print a;
	</source>		</source>
	~~output : [5, 5, 5, 5, 4, 4, 4, 4, 4, 4]~~

			output : < br />
			['1', '2', '3', '4', '5', '6', '7', '8', '9'] <br />
			['1', 5, 5, 5, '5', '6', '7', '8', '9']
