python因式分解

Python因式分解可以使用以下代码实现：

n = int(input("请输入一个正整数："))
x = 2
factors = []
while n > 1:
    if n % x == 0:
        factors.append(x)
        n = n / x
    else:
        x = x + 1

print("该数的因式分解为：", end="")
for i in range(len(factors)):
    if i != len(factors) - 1:
        print(factors[i], "*", end=" ")
    else:
        print(factors[i], end="")

这段代码首先通过`input()`函数获取用户输入的一个正整数，并将其存储在变量n中。然后，通过循环从最小的素数2开始尝试去除n，并将能整除的因子存储在factors列表中。最后，将factors中的因子按照乘法表达式的形式输出。
