在循环中动态实例化Player类

Question

I am making a simple Python game. I have a text file with the following on each line:

player name, player IP, player health, player items

I have a loop which goes through each line in the file and get the variables for each player (each line in the text file is a player).

I have a class called Player , I need one instance of this for each player.I wish to have a list which contains all the instances of Player.

Answer 1

Sven has a good answer but you can even do away with the first line and just do

config = [line.split(',') for line in open("config")]

Or as you may want to actually instantiate the players:

config = [Player(line.split(',')) for line in open("config")]

If you're going to be doing a lot more csv configs for your game, look into the csv module.

Answer 2

What you need to do is use the map function to call the constructor and expand what you've read in the config file as the parameters of the instantiation:

players = map(lambda tuple_args: Player(*tuple_args), (line.split(',') for line in open("config"))) 

or simpler using list comprehension:

players = [Player(*(line.split(','))) for line in open("config")]
