Error in `./python': free(): invalid next size (fast) 准备阶段 Linux配置Python一般使用源码编译安装的方式,最万能也最坑,那么在开始前可以首先使用 sudo yum -y update # 可以不做 1. 先更新下,升级所有包同时也升级软件和系统内核,如果担心系统内核发生变化可以不执行该命令,接下来安装一些工具 sudo yum...

if free.count(True) > 5: 布尔表达式永远不会计算为True。随着错误的传播,没有位置被标记为点,结果我们获得了一个只有墙的网格。 同样结局的一个缺陷是省略了free.count中的函数调用。不幸的是,对于许多编程学徒来说,下面是 Python 2.7 中的一个合法表达式: if free.count < 5: 尽管前面的表达式在 Pytho...

ctypes 是Python标准库中提供的外部函数库，可以用来在Python中调用动态链接库或者共享库中的函数，比如将使用大量循环的代码写在C语言中来进行提速，因为Python代码循环实在是太慢了。大致流程是通过 ctypes 来调用C函数，先将Python类型的对象转换为C的类型，在C函数中做完计算，返回结果到Python中。这个过程相对是比较...
