如何打印在Python中系数已知的n次多项式的字符串表示？

def print_polynomial(coefficients):
    degree = len(coefficients) - 1
    polynomial = ""

    for i, coefficient in enumerate(coefficients):
        if coefficient != 0:
            if i == 0:
                term = f"{coefficient}"
            elif i == 1:
                term = f"{coefficient}x"
            else:
                term = f"{coefficient}x^{i}"

            if i < degree:
                term += " + "
            
            polynomial = term + polynomial

    print(polynomial)

# 示例用法
coefficients = [2, -3, 0, 1]
print_polynomial(coefficients)
