This may be something like what you are trying to achieve:

# untested
def fx(arg):
     pass
def fy(arg):
     pass
def fdefault(arg):
     pass

funcmap = {
    'x1': fx,
    'x2': fx,
    'y' : fy,
}

eventlist = "y x2 x2 x1 y".split()
for ev in eventlist:
     efunc = funcmap.get(ev, fdefault)
     if efunc(t): # what is t????
         # do something
