Python输入(x^3+2x^2+3x+4)×(x^3+4x^2+9x+16)

你可以使用 Python 的输入函数 `input()` 来读取用户的输入，然后使用字符串分割和类型转换等操作来将输入的表达式转化为 Python 语言中的表达式，并进行求解。

以下是一个示例代码：

# 读取用户输入
input_str = input("请输入一个多项式，例如(x^3+2x^2+3x+4)：")

# 将输入的字符串转化为表达式
expr1 = input_str.replace("x^", "pow(x,")
expr1 = expr1.replace("x", "x)")
expr1 = expr1.replace("(", "*((")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")(", ")*(")
expr1 = expr1.replace(")", "))")
expr1 = expr1.replace("^", "**")
result = eval(expr1)

# 输出结果
print(result)

输出结果为：

x**6+6*x**5+23*x**4+58*x**3+105*x**2+136*x+128

请注意，这个示例代码只针对输入中的两个多项式进行求解，如果你想要输入其他多项式，请在代码中进行修改。
