Ah. Check your indentation: it appears that the definition of getday() is
within the body of the class initializer __init__().
What ends up happening is that getday() is no longer a method definition,
but an inner function definition. Python makes it very easy to define
functions within functions, and what you have in effect is a function
definition within the __init__() method definition, which is probably not
what you want.
Tip: if possible, always use four spaces for your indentation to make this
error easier to see. Don't skimp on this. *grin*
Also note that Python's class system does not make using 'self' optional,
so when you're initializing the attributes of an instance in __init__:
remailfile = open('U:\Bounce20.txt', 'r')
resendfile = open('resend.txt', 'w')
EmailReport = open('erprt.txt', 'w')
you need to tell Python not to treat these as local variables assignments.
self.remailfile = open('U:\Bounce20.txt', 'r')
self.resendfile = open('resend.txt', 'w')
self.EmailReport = open('erprt.txt', 'w')
As a side note: escape the backslashes in your literal strings: otherwise,
you'll run into issues. I'm assuming you're coming from a Java or C++
background, but if you need this point elaborated, please ask, and we'll
go into more detail.
If you have more questions, please feel free to ask. Good luck!
