Assuming you only want to look inside the types that you're
replacing...
def transform(source, from_type, to_type):
if not isinstance(source, from_type):
return source
else:
return to_type(transform(x, from_type, to_type)
for x in source)
def list2tuple(source):
return transform(source, list, tuple)
def tuple2list(source):
return transform(source, tuple, list)
