global variable usage
<p>I have one basic question,I am declaring xmlfile as global in xml function,can I use it in another subroutine without any issues?does the order of subroutines matter?</p>

<pre><code> def xml():

        global xmlfile
        file = open('config\\' + productLine + '.xml','r')
        xmlfile=file.read()
 def table():
            parsexml(xmlfile)
</code></pre>
