True. Python tends to overload its keywords, which leads to weird expression.
Also weird, again using "then":

	try:
	    n = 1 + 1
	except Exception, e:
	    print ("*error*")
	else:
	    print (n)

actually means

	try:
	    n = 1 + 1
	then:
	    print (n)
	except Exception, e:
	    print ("*error*")
