去除印刷品的凹痕正在打破循环

Answer 1

设置一个变量而不是打印。使用 break 来停止循环而不是 return。

然后在最后打印变量。

def cubroot(n):
    if n == 0:
        return 0
    elif range < 0:
        n = -n
    for p in range(n):
        if n>p*p*p:
            d=n-(p*p*p)
            result = f"{p} not exact with difference {d}"
        elif (p*p*p)==n:
            result = f"{p} exact"
            break
    print(result)

Answer 2

你不应该返回打印语句：只返回你想要打印的值并打印整个函数而不是这个

return print(p,"exact!")

但是这个

return int(p) + " exact!"

Answer 3

这是为了满足您的要求而更改的功能：

def cubroot(n):
    for p in range(n):
        if (n ** (1 / 3) - 1) ** 3 < p ** 3 < n:
            d = n - p ** 3
            print(p, "not exact with differnece", d)
        elif p ** 3 == n:
            return print(p, "exact!")

cubroot(2000)

表达式 p ** 3 等价于 p * p * p。我基本上改变了你的情况

p ** 3 < n

成为

(n ** (1 / 3) - 1) ** 3 < p ** 3 < n

另一种方式是：

def cubroot(n):
    for p in range(n):
        if p ** 3 < n and (p + 1) ** 3 > n:
            d = n - p ** 3
            print(p, "not exact with differnece", d)
        elif p ** 3 == n:
            return print(p, "exact!")

cubroot(2000)

如何仅打印最后一个输出？
