Here, typecode is what we use to define the type of value that is going to be stored in the array. Some of the common typecodes used in the creation of arrays in Python are described in the following table. Type Code C Type Python Data Type Minimum Size in Bytes ‘b’ signed char...
window.maxsize(400,400) 设置窗口被允许调整的最大范围,即宽和高各400 window.attributes("-alpha",0.5) 用来设置窗口的一些属性,比如透明度(-alpha)、是否置顶(-topmost)即将主屏置于其他图标之上、是否全屏(-fullscreen)全屏显示等 window.state("normal") 用来设置窗口的显示状态,参数值 normal(正常显示),icon...
log[2]n,每个大小为n/2^j 的子问题有 2^j 个。为了计算总操作次数,我们需要知道单个合并两个子数组所包含的操作次数。让我们来数一下之前 Python 代码中的操作次数。我们感兴趣的是在进行两次递归调用后的所有代码。首先,我们有三个赋值操作。然后是三个 while 循环。在第一个循环中,我们有一个 if else ...
