如何根据Bytes拆分字符串值？

def split_string_by_bytes(string, num_bytes):
    # 将字符串转换为字节数组
    byte_array = string.encode('utf-8')
    
    # 根据指定的字节数进行切片
    split_bytes = [byte_array[i:i+num_bytes] for i in range(0, len(byte_array), num_bytes)]
    
    # 将切片后的字节数组转换为字符串
    split_strings = [bytes(chunk).decode('utf-8') for chunk in split_bytes]
    
    return split_strings

string = "Hello, 你好！"
num_bytes = 5

split_strings = split_string_by_bytes(string, num_bytes)
print(split_strings)

['Hello', ', 你', '好！']
