解析 正确答案:8,20 解析:本题考查while循环和++运算符的运用。x=O符合条件x<15,则执行y++,x+=+y后,y=1,x=0+2=2后y=2,符合条件继续循环,y=3,x=x+4=6后y=4,再循环y=5,x=x+6=6+6=12后,y=6,继续循环y=7, x=x+8=12+8=20,此时y=8。

1 x = int(input("输入x的值:")) 2 y = 0 3 for y in range(0, 100): 4 if x == y: 5 print ("找到数字:", x) 6 break 7 else: 8 print("没有找到") 【代码说明】 第1行代码捕获用户输入的值,并把该值转换为int类型,赋值给变量x。 第2行代码定义一个变量y,变量y用于暂存需要遍历...
x+=++y得到y=2,x=2 第二次循环 y++得到y=3 x+=++y得到y=4,x=6 第三次循环 y++得到y=5 x+=++y得到y=6,x=12 第四次循环 y++得到y=7 x+=++y得到y=8,x=20 循环结束

x = 0时，执行y++后，y = 1，执行x += ++y后，y = 2，x = 2 x = 2时，执行y++后，y = 3，执行x += ++y后，y = 4，x = 6 x = 6时，执行y++后，y = 5，执行x += ++y后，y = 6，x = 12 x = 12时，执行y++后，y = 7，执行x += ++y后，y = 8...
(Supplementary Fig.3A). However, beyond a certain threshold, we found increasing the number of CG calls had a minimal effect reducing the margin of error. An asymptotic model described by the equationsy = 1.207/√xandy = 2.109/√x, for sperm and muscle respectively, was used to ...
While作为并列连词，意思为而，然而，表前后意义上的对比或转折。(x=y)5是5X=5Y是一个数学方程式。
因为y++，x+=++y;是逗号表达式，所以最终值是x+=++y;还有x+=++y等价于x=x+(++y)0<15 y=1,x=0+2;//x=2,y=2 2<15 y=3,x=2+4;//x=6,y=4 6<15 y=5,x=6+6;//x=12,y=6 12<15 y=7,x=12+8;//x=20,y=8 20<15 不成立 输出：y=8,x=20 ...
