forloop.revcounter0:获取从0开始的反向循环的计数器或索引。 这些计数器的使用方法与forloop.counter类似。 总结 在Django模板中,使用for循环计数器(如forloop.counter)可以方便地获取当前循环的计数器或索引。此外,Django模板还提供了其他几个有用的for循环计数器,可以根据实际情况进行选择。
django 模板语言共分四部分:变量 标签 注释 过滤器。 在标签里面使用for循环时,如何获取当前for循环次数,使用模板变量{{forloop.counter}}

linecount = 0; // ...and reset the line counter } } std::cout << std::endl; } 分析: 当运行这个程序时,循环会结束的比预期的早。 最后,radius的值显示为2.8,而不是3.0。 这是因为把0.2加到2.8时,结果大于3.0。原因是0.2表示为二进制浮点数时,有一个非常小的错误,不能把0.2准确地表示为二进制...
