我有乙個主列表，它基於2個子列表。我想用「search_value」引數建立乙個函式，並列印「search_value」項的索引位置，包括子列表的列表索引。在
示例：grocery = ["juice", "tomato", "potato", "banana", "milk", "bread"]
clothes = ["shirt", "pant", "jacket", "sweater", "hat", "pajama", "t-shiraz", "polo"]
master_list = [grocery, clothes]
預期結果：

master_list = [grocery, clothes]

P2P打洞中遇到的問題
裝置a通過一台聯通的路由器上網，裝置a通過有線連線路由器 裝置b是一台手機是移動2g 協助伺服器是電信網路 附 裝置a和裝置b經過ip.cn 測試發現各自的外網位址是 裝置a 221.4.212.2，聯通ip，相對固定 裝置b 117.136.33.128，移動ip，手機網路經常變動 但是通過伺服器...
CAP理論中的P含義
乙個分布式系統裡面，節點組成的網路本來應該是連通的。然而可能因為一些故障，使得有些節點之間不連通了，整個網路就分成了幾塊區域。資料就散布在了這些不連通的區域中。這就叫分割槽。當你乙個資料項只在乙個節點中儲存，那麼分割槽出現後，和這個節點不連通的部分就訪問不到這個資料了。這時分割槽就是無法容忍的。提高...
P2P網路中的節點發現
在p2p網路中，要發現並連線其他節點，常見的是通過種子節點連線到網路，然後通過種子節點獲取其他節點的位址。以太坊的種子節點在cmd swarm bootnodes.go中定義，hpb的種子節點在config networkconfig.go中定義 以hpb節點為例說明 以太坊基本是一樣的。1 節點啟...
