将整数列表转换为字节/ascii字符串，然后再转换回来？快地?

def int_list_to_bytes(int_list):
    return bytes(int_list)

def int_list_to_ascii_string(int_list):
    return ''.join(chr(i) for i in int_list if 0 <= i < 128)

def bytes_to_int_list(byte_data):
    return list(byte_data)

def ascii_string_to_int_list(ascii_str):
    return [ord(char) for char in ascii_str]

# 示例整数列表
int_list = [65, 66, 67, 68, 69]

# 转换为字节
byte_data = int_list_to_bytes(int_list)
print(f"Byte data: {byte_data}")

# 转换回整数列表
recovered_int_list = bytes_to_int_list(byte_data)
print(f"Recovered int list: {recovered_int_list}")

# 转换为ASCII字符串
ascii_str = int_list_to_ascii_string(int_list)
print(f"ASCII string: {ascii_str}")

# 转换回整数列表
recovered_int_list_from_ascii = ascii_string_to_int_list(ascii_str)
print(f"Recovered int list from ASCII: {recovered_int_list_from_ascii}")

import struct

def int_list_to_bytes_fast(int_list):
    return struct.pack(f'{len(int_list)}B', *int_list)

def bytes_to_int_list_fast(byte_data):
    return list(struct.unpack(f'{len(byte_data)}B', byte_data))
