如何使用python以二进制补码的形式打印有符号整数作为十六进制数？

def to_twos_complement(num, bits):
    if num >= 0:
        return bin(num)[2:].zfill(bits)
    else:
        return bin(2**bits + num)[2:]

def binary_to_hex(binary_str):
    return hex(int(binary_str, 2))[2:].upper()

def print_hex_twos_complement(num, bits):
    binary_str = to_twos_complement(num, bits)
    hex_str = binary_to_hex(binary_str)
    print(hex_str)

# 示例：以二进制补码形式打印有符号整数-10作为十六进制数
print_hex_twos_complement(-10, 8)
