I zoned out on your question and created a very simple flipper.
Although it will not solve your problem maybe someone looking for a
simpler version may find it useful as a starting point. I hope it
proves useful. I'll post my simple flipper here:
s = 'cond(1,savv(grave(3,2,1),y,x),maxx(c,b,a),0)'
def argFlipper(s):
''' take a string of arguments and reverse'em e.g.
>>> cond(1,savv(grave(3,2,1),y,x),maxx(c,b,a),0)
-> cond(0,maxx(a,b,c),savv(x,y,grave(1,2,3)),1)
'''
count = 0
keyholder = {}
while 1:
if s.find('(') > 0:
count += 1
value = '%sph' + '%d' % count
tempstring = [x for x in s]
startindex = s.rfind('(')
limitindex = s.find(')', startindex)
argtarget = s[startindex + 1:limitindex].split(',')
argreversed = ','.join(reversed(argtarget))
keyholder[value] = '(' + argreversed + ')'
tempstring[startindex:limitindex + 1] = value
s = ''.join(tempstring)
else:
while count and keyholder:
s = s.replace(value, keyholder[value])
count -= 1
value = '%sph' + '%d' % count
return s
print argFlipper(s)
