I would use a lambda for this, like:
def makeidentical(linenumber):
print "the linenumber is: %d" % (linenumber)
for day in datelist:
a=datelist.index(day)
if a>0:#on every line exept the first
identicalbutton=Button(frame2,text="=",command=lambda :
makeidentical(a))
identicalbutton.grid(row=a+2,column=3,sticky=W)
frame2widgets.append(identicalbutton)
I hope this helps
Michael
