小编use*_*721的帖子

抱歉这个愚蠢的问题.我在PHP上编程,但在Python上发现了一些很好的代码,并希望在PHP上"重新创建"它.但我对这条线路感到非常沮丧

self.h = -0.1    
self.activity = numpy.zeros((512, 512)) + self.h
self.activity[:, :] = self.h

但我不明白是什么

[:, :]

意思.

此外,我无法"谷歌它".

完整代码

import math
import numpy
import pygame
from scipy.misc import imsave
from scipy.ndimage.filters import gaussian_filter


class AmariModel(object):

    def __init__(self, size):
        self.h = -0.1
        self.k = 0.05
        self.K = 0.125
        self.m = 0.025
        self.M = 0.065

        self.stimulus = -self.h * numpy.random.random(size)
        self.activity = numpy.zeros(size) + self.h
        self.excitement = numpy.zeros(size)
        self.inhibition = numpy.zeros(size)

    def stimulate(self):
        self.activity[:, :] = self.activity > 0

        sigma = …
