basic doubt

[madhuri vio]

def h(self,event):
    handle = open("myco.fasta","r")
    for seq_record in SeqIO.parse(handle, "fasta"):
         messenger_rna = coding_myco.fasta.transcribe()
         han1 = open("mycorna.fasta","wU")
         han1.close()
         return self.messenger_rna


the error is...

File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1413, in __call__
    return self.func(*args)
TypeError: h() takes exactly 2 arguments (0 given)
