Help with python list-comprehension
- by leChuck
A simplified version of my problem:
I have a list comprehension that i use to set bitflags on a two dimensional list so:
s = FLAG1 | FLAG2 | FLAG3
[[c.set_state(s) for c in row] for row in self.__map]
All set_state does is:
self.state |= f
This works fine but I have to have this function "set_state" in every cell in __map. Every cell in __map has a .state so what I'm trying to do is something like:
[[c.state |= s for c in row] for row in self.map]
or
map(lambda c: c.state |= s, [c for c in row for row in self.__map])
Except that neither works (Syntax error). Perhaps I'm barking up the wrong tree with map/lamda but I would like to get rid on set_state. And perhaps know why assignment does not work in the list-comprehension
