</a>><br><br><br>I don't think there's any need for eval - I'll leave the sermon about why eval is a Bad Thing for someone else - and if your objects are going to spend most of their "lives" in a list or dictionary, they don't really need meaningful individual names. (I mean, instead of naming each one class1, class2, etc. you can simply refer to them as classDict[1], classDict[2], etc. or classList[1], etc.)
<br><br>How's this:<br>#====================================<br>class thingy():<br> example = "Just testing - "<br> def __init__(self, num):<br> self.example = self.example + str(num)<br><br>thang = {}
<br>for x in range(1,4):<br> thang[x] = thingy(x)<br><br>for item, value in thang.iteritems():<br> print item, value.example<br>#=====================================<br><br><div class="gmail_quote"><div><div></div>

Hi there.<br><br>I need to instantiate objects on the fly and put the in a list/dict for later use. I was thinking of this:<br><br>objectlist = []<br>newobjectname = "object1"<br>classname = "class1" + "()"
<br>objectlist.append(newobjectname = eval(classname) )<br>objectlist[0].method("hello world")<br clear="all"><br>Can this be done? If not, is there a work around or some design pattern for this situation?<br><br>
