我有一個問題，然后通過套接字發送一個串列，
它必須是類似位元組的物件，好吧，我可以將其轉換為
字串然后執行.encode("utf-8")，但
這里的問題是它是字串，并且很難從中重建它的
串列字串，literal_eval()從ast庫
沒有作業然后我有這樣的事情：
[("Something", datetime.datetime(2021, 12, 11, 0, 0))]
這就是問題，我必須擁有這些物件，我的
問題是如何發送 python 物件而無需
將其轉換為字串，或者
像 JSON這樣的某種物件符號？
這可以在
Python Socket Documentation 中的基本套接字服務器上進行測驗。
失敗的文字 Eval：
from ast import literal_eval
new_line = literal_eval("[(2, 2.0, 'MS-0150886', 'B1A', 'MP5 TEST IS HERE!', None, None, datetime.datetime(2021, 8, 13, 0, 0), datetime.datetime(2021, 8, 13, 0, 0), 38.0, None, None, '1', None, None, None, 1.0, None, 1.0, 'KS-005418-2', 'KS-005419-1', 'SPRAWDZ 9', None, None, None, 1.0, None, None, None, None, 1.0, 1)]")
print(new_line)
print(type(new_line))
錯誤：

uj5u.com熱心網友回復：
你試了pickle嗎？
import pickle
# Client
data = [("Something", datetime.datetime(2021, 12, 11, 0, 0))]
s.sendall(pickle.dumps(data))
# Server
data = pickle.loads(conn.recv(1024))
print(data)
