在Python中,if语句用于根据条件执行特定的代码块。any()是一个内置函数,用于判断可迭代对象中是否存在至少一个为True的元素。如果存在至少一个为True的元素,则返回True;否则返回False。 使用any()命令可以简化条件判断的过程,特别适用于需要判断多个条件中是否至少有一个为True的情况。以下是使用any()命令的示例代码:...

在Python中没有switch语句。你可以使用if..elif..else语句来完成同样的工作(在某些场合,使用 字典会更加快捷。) 在C/C++中,如果你想要写for (int i = 0; i < 5; i++),那么用Python,你写成for i in range(0,5)。你 会注意到,Python的for循环更加简单、明白、不易出错。 即便是整数也被作为对象(属于...

据官网介绍,pipx 是安装并运行 Python 终端用户应用(end-userapplications)的工具。终端用户应用,其实可以理解为用 Python 编写的命令行工具,可以直接从命令行调用的那种。有点类似 Mac 下的 brew,类似 JavaScript 的 npx,和 pip 也很像,只是专门用来安装命令行工具库。pipx 之所以存在,是因为 Python 和 PyPI 支...
在vim script 里面跑的那个语言就是 vim language( VimL )。你能够像使用其他编程语言一样,用 VimL 来写程序。我简单地写了一个: function! RenameByVim() echo("开始处理...") let start_time = localtime() let lnum = 1 let c = 0 let num = 0 while lnum <= line("$") let con = ge...
