你的变量K没有递增啊，正确代码如下def l_sum1(k): a = 0 b = 0 while b <= k: a += b b += 1 return aprint(l_sum1(100))

T = (1, 'CH', [3, 4])
T = list(T)
T[2]=tuple(T[2])
print(tuple(T))
T = list(T)
T[2]=tuple(T[2])
print(tuple(T))

取模运算的结果就是除法运算的余数，99/30=3余9所以99%3的结果就是9，==>没什么用就是表示个箭头，后面是这行程序运行的结果，#是注释，#后面的部分只会作为文本显示，不作为程序运行

额，，，，，短路计算，a and b 如果a是false 那么输出就是a 如果a是true 那么输出无论b是true或者false，都是b。你这里a=“pd”然后print（“hello”，a and “world”）a已经赋值字符串pd应该是true！
