it's harder to really be confident that the code will do what it's supposed to 更難確信程式碼會達到預期的效果 we'll do a quick rundown of the many concepts around testing 我們將對測試的許多概念做一個快速的介紹  Log files contain a lot of useful information, particularly when you're trying to debug a tricky problem that's happening on a computer 日誌檔案包含許多有用的資訊，尤其是當您試圖除錯電腦上發生的棘手問題時 To be able to process the output of commands, we'll set a parameter called capture output  This can be handy for system commands 這對於系統指令來說很方便 Software testing is a process of evaluating computer code to determine whether or not it does what you expect it to do 軟體測試是一個評估電腦程式碼的過程，以確定(判斷)程式碼是否達到您所期望的功能 if we just want to run a command and only care about whether or not it was successful. 如果我們只想執行指令，而只關心指令是否成功執行 which means that our script has no control over it 這表示我們的腳本無法控制它 helping us create a custom vision-language model tailored to our specific tasks. 幫助我們建立專為特定任務量身打造的客製化視覺語言模型 These are parameters that are passed to a program when it started. 這些是程式啟動時傳給程式的參數 Another common way of providing information to our programs is through command line arguments 為程式提供資訊的另一種常見方式是透過命令列參數 The most commonly used shell on Linux is called bash. Linux 上最常用的 shell 叫做 bash You are allowed to refer to your completed lab notes during the quiz 您可以在測驗時參考已完成的實驗筆記 Please note that there is a graded quiz that follows this lab. You must complete the lab before attempting the quiz. The quiz will assess your comprehension of the key concepts and procedures covered in the lab 請注意，本實驗後還有一個分級測驗。您必須先完成實驗，才能參加小測驗。測驗將評估您對本實驗所涵蓋的主要概念和程序的理解程度 Wildcard: A character that can match more than one character  Applicable from November 28 to December 5, 2024, 11:59 PM (UTC +0) 適用於 2024/11/28...  Not applicable to services that have been doubled before. 不適用於之前已加倍的服務 This module includes a bunch of different functions that can help manipulate strings 這個模組包含了一堆不同的函式，可以幫助操控字串 reserved characters 保留字元 But thankfully, the principles are always the same 但值得慶幸的是，原則總是相同的 Implementation 實現; 建置; 施作; 實作; 執行 a bunch of; a ton of; plenty of 許多; 多種; 很多

• There are plenty of others you'll be using soon 您很快就會用到許多其他的

It's enough to make you growl 您看到潛在的問題了嗎？這足以讓你咆哮 we get some hands-on practice with all this 我們可以親身體驗這些 the interpreter raises an error 直譯器將產生錯誤
absolute path ; relative path 絕對路徑;相對路徑 Is it worth the time 是否值得花時間 Without virtual environments, managing these dependencies could become a nightmare 如果沒有虛擬環境，管理這些依賴關係可能會變成一場惡夢 This term stands for Integrated Development Environment, and usually refers to a code editor 這個詞代表整合開發環境，通常是指程式碼編輯器 when we run the Python 3 command, we get an interactive interpreter. 當我們執行 Python 3 指令時，我們會得到一個互動式的直譯器 Interpreted vs. Compiled Languages 直譯式與編譯式程式語言 In my job as a sysadmin, I mainly work with the Linux operating system 在我的系統管理員工作中，我工作主要使用 Linux 作業系統 You may have also heard of Unix 您可能還聽過 Unix We refer to these different flavors of Linux as distributions. 我們稱這些不同風格的 Linux 為發行版 They are tempted to spend a lot of time trying to solve the problem on their own 他們很想花很多時間嘗試自己解決問題
To check that our code is doing everything it's supposed to do 要檢查我們的程式碼是否做了所有該做的事 In this scenario, it makes sense to use a set to store the current users 在這種情況下，使用集合來儲存目前的使用者是合理的 I was happy with it, the user was happy with it. 我很滿意，使用者也很滿意 We're gonna dive into object-oriented programming 我們要深入瞭解物件導向程式設計 It's your call ; It's up to you 由你決定 we add, remove, or change the elements inside that box 我們新增、移除或變更該方塊內的元素 it doesn't matter how long each string is on its own. What matters is how many elements the list has 每個字串本身有多長並不重要。重要的是 list 有多少個元素 indicate ; represent 表示
