For what you're trying to accomplish, you need to add a `global'
statement--and pass the representation of seqno to the print
statement or use the printf() support.
def SomeFunc():
global seqno
print 'Using serial #' + `seqno`
# print 'Using serial #%d' % seqno
seqno = seqno+1
If seqno were not a global variable, you would have have an
assignment of seqno before it could be used (otherwise seqno is not in
the namespace?). Here's this less interesting version of SomeFunc().
def SomeFunc():
seqno = 0
print 'Using serial #' + `seqno`
seqno = seqno+1
