回复了 eric_zyh 创建的主题 问与答 一个数学方程式求解: 2^(x-3) = x
输入:Solve[2^(x - 3) == x, x]
结果:{{x -> -(ProductLog[-(Log[2]/8)]/Log[2])}, {x -> -(
ProductLog[-1, -(Log[2]/8)]/Log[2])}}
@zentorwie 我在搜索解决方式的时候,也看到了这篇文章

回复了 sneezry 创建的主题 iDev 没有 MacBook 的前提下有什么比较好的方法使用 xcode 开发 iOS 吗
Mac mini,至于虚拟机,还是玩玩吧,不能干活
在GNOME3中搜索 nm

回复了 artwalk 创建的主题 程序员 大家平时怎么码代码的?
第2种,我是业余选手
@binux 你的意思是说,所有定义的self.XXX是函数内的(self)决定的,突然明白了。哈哈,被打醒了,ThankYou,谢谢你的耐心~~
@binux
class AAA():
········self.a='5'
········def go(self):
················pass


b=AAA()
b.a

---------
为什么不可以在class内和def平行关系,定义self.XXX这种实例化变量?
