程序段实现的是1到10之间,以步长为3各个数字的累加和,即:1+4+7+10=22,分步执行过程如下:初始值:i=1,s=0;一次循环:s=s+i=1,i=i+3=4;二次循环:s=s+i=5,i=i+3=7;三次循环:s=s+i=12,i=i+3=10;四次循环:s=s+i=22,i=i+3=13,至此循环结束,变量s的值为22,i的值为13.故答...
此段代码时一个DO While(条件)语句,loop意思是:符合条件继续循环.初始化s=0,i=0<=11成立,执行第一次,此时s=0,i=3,符合条件;执行第二次:此时s=0,i=6,符合条件;执行第三次:此时s=0,i=9,符合条件;执行第四次:此时s=0,i=12,条件不满足退出循环.故选:D. Visual Basic是一种面向对象的编程...

You can use Unicode characters even in Python identifiers, but then there’s the question of whether or not that’s an advisable thing to do.In case you’re prefixing the string with r, like in r"raw\text", then the backslash loses its special meaning. This is especially convenient ...
line 8 is not hit. I plan to use this when I want to stop at the first iteration of a loop, but only if an outer condition is met. Previously, I needed to enable one breakpoint until the outer condition was met, and only after that was hit enable a breakpoint inside the loop. ...
