在IronPython for ASP.NET 中改写 print 以方便调试 python 语言中最方便的莫过于 print 语句,搭配 dir() 等函数,能随时查看对象的属性,内容等。而 IronPython for ASP.NET 的环境下 print 是不会显示出来的。用下面的办法,可以改写输出流到 web 页面上。 先在App_Script 目录下建立一个 debug.py,内容如下...

readline()是Python中的文件对象方法,用于从文件中读取一行内容。当文件中没有更多的行可读时,readline()会返回一个空字符串。 print()函数用于将内容输出到控制台。当print()函数的参数是一个空字符串时,它会输出一个空行。 综上所述,当执行print(readline())时,如果readline()已经读取到文件末尾,则print(...
