3、html页面效果如下: 4、在前端循环处加上forloop,效果如下,可见每一项都从1开始计数: 5、修改一下前端,forloop.counter0,可以从 0 开始计数,跟列表的索引可以一一对应,这个比较重要: 6、通过tag返回forloop的值: 创建tag: @register.simple_tag def getforloop(column,forloop): return forloop 在前端页面...

See how easy it was to convert the while loop into an equivalent for loop? How does it work, you ask? Well it's simple. In a for loop, the integer mentioned inside the range function is the range or the number of times the control needs to loop and execute the code in the for ...
