面对这样一个要求,在没有学习循环指令之前,你可能会一段一段的写,需要写54段程序,今天,我们来尝试下用FOR指令来写,如下图。 每次进行扫描都会先把Z0清0,然后进入循环(54次),第一遍Z0=0,这时X000Z0的地址是X000,Y000Z0的地址是Y000,X000触发Y000线圈并形成自锁,通过INC指令Z0自加1;第二遍,Z0等于1,这...
for循环里的range()函数要写成range(1,53),这样变量x就会依次装入1,2,3,...52了。for循环执行的是③和④组成的代码块,代码③可能有点费解,不过我们可以这么想:leiji就像一个银行账户(最开始的时候是0元),第一周的时候你干家务挣的钱加上送奶的钱再减去消费的钱,就是你第一周累积的钱leiji(存银行里)...
