Question

I’ve got a piece of code which contains a for loop to draw things from an XML file;

   for evoNode in node.getElementsByTagName('evolution'):       evoName    = getText(evoNode.getElementsByTagName(        'type')[0].childNodes)       evoId      = getText(evoNode.getElementsByTagName(      'typeid')[0].childNodes)       evoLevel   = getText(evoNode.getElementsByTagName(       'level')[0].childNodes)       evoCost    = getText(evoNode.getElementsByTagName('costperlevel')[0].childNodes)        evolutions.append('%s x %s' % (evoLevel, evoName)) 

Currently it outputs into a list called evolutions as it says in the last line of that code, for this and several other for functions with very similar functionality I need it to output into a class instead.

class evolutions:     def __init__(self, evoName, evoId, evoLevel, evoCost)         self.evoName = evoName         self.evoId = evoId         self.evoLevel = evoLevel         self.evoCost = evoCost 

How to create a series of instances of this class, each of which is a response from that for function? Or what is a core practical solution? This one doesn’t really need the class but one of the others really does.

Answer 1

for evoNode in node.getElementsByTagName('evolution'):   evoName      = getText(evoNode.getElementsByTagName('type')[0].childNodes)   evoId      = getText(evoNode.getElementsByTagName('typeid')[0].childNodes)   evoLevel   = getText(evoNode.getElementsByTagName('level')[0].childNodes)   evoCost      = getText(evoNode.getElementsByTagName('costperlevel')[0].childNodes)    temporaryEvo = Evolutions(evoName, evoId, evoLevel, evoCost)   evolutionList.append(temporaryEvo)    # Or you can go with the 1 liner   evolutionList.append(Evolutions(evoName, evoId, evoLevel, evoCost)) 

I renamed your list because it shared the same name as your class and was confusing.
