Looking for a way around a logical error in a pygame program 我正在自学 pygame,我正在尝试制作一个程序,该程序可以在单击正方形后切换其颜色。问题是,如果用户在方块上单击超过 1/60 秒,则方块将开始在蓝色和橙色之间循环,这是我选择的两种颜色。下面是应该切换正方形颜色的代码: ifevent.type==pygame.MOUS...
Logical Errors in Python occur in the code when everything in the code is syntactically and semantically correct, but the desired output is missing because of some logical mistake done by the programmer. These are very difficult to find as there is no error thrown by the compiler. And the p...
This is inPythoncoded. Of course I could it write in C, but it will be no help which make sense for you. You have to code with structure. Divide the project on small steps and solve them. And this step by step with testing of each step. You should make first a skizze of algorith...

logical_not是一个逻辑运算符,用于对输入进行逐元素的逻辑取反操作。在布尔数组中,它将True变为False,将False变为True。 然而,在数值数组中,logical_not则将0视为...
Python编程基础:第九节 逻辑运算Logical Operators 第九节 逻辑运算Logical Operators 前言 实践 前言 常用的逻辑运算共分为三种:与(and)、或(or)、非(not)。与运算就是同真才真,有假则假;或运算就是有真则真,同假才假;非运算就是真变假,假变真。我们接下来举个例子加以分析。 实践 我们从键盘获取输入...

R语言如何修复:Argument is not numeric or logical: returning na 在这篇文章中,我们将看到如何在R语言中修复参数不是数字或逻辑的情况下返回na。 这是你在R中可能面临的警告信息,其形式如下。 警告信息。 In mean.default(dataframe) : argument is not numeric or
