Python chain Examples

Example #1

File: traverse.py Project: alhirzel/sympy

def top_down(brule, fns=basic_fns):
    """ Apply a rule down a tree running it on the top nodes first """
    return chain(do_one(brule, identity),
                 lambda expr: sall(top_down(brule, fns), fns)(expr))

Example #2

File: traverse.py Project: vchekan/sympy

def top_down(brule, fns=basic_fns):
    """ Apply a rule down a tree running it on the top nodes first """
    return chain(do_one(brule, identity),
                 lambda expr: sall(top_down(brule, fns), fns)(expr))

Example #3

 def chain(self,f):
     return core.chain(self,f)
