You will have to provide more code than this. The traceback error you
are getting is coming from Tk's event loop when it tries to execute your
callback. Your callback is defined as having two parameters, but
whatever is calling it from within Tk is expecting it to have no
parameters. Without seeing a complete (but minimal!) code example that
folks can run on their own computers and replicate your problem, there's
no way for any of us to help you debug your code.
Given the nature of your queries, I assume your are most likely in
academia, doing bioinformatics research. You would be wise to seek out
help from a computer science student or professor. In fact you're
likely to receive more help by doing that than from this mailing list,
at least at this stage.
In your next post, please do at least the following things:
1. Make the e-mail subject clear, precise, and descriptive. "basic
doubt" or "gui doubt" is *simply not acceptable*. Instead you might
say, "How can I run a function when I click a button in Tk?" or "What
does this traceback mean?"
2. Post enough code so that someone can cut and paste it and run it
through python to duplicate your error.
If you don't, I'm afraid that 95% of the list members are going to
silently delete your e-mails, which will no doubt cause you much
frustration. Many have already blocked your e-mail address.
