[英]Python - Assign class attribute to a variable
我正在制作一個類似應用程序的字典,根據翻譯開關,屏幕顯示翻譯或原始單詞代碼如下所示:
PS:“textFunction(text)”只是一個將文本顯示到屏幕的函數。 PS:“wordList”是詞類實例列表
class Word:
def __init__(self, original, translation):
self.original = original
self.translation = translation
translation = False
if translation == False:
wordDisplayed = .original
elif translation == True:
wordDisplayed = .translation
textFunction(wordList[X].wordDisplayed)
但是,這不起作用。 我怎么能解決這個問題?
你會使用getattr
:
wordDisplayed = "translation" if translation else "original"
textFunction(getattr(wordList[X], wordDisplayed))
雖然“getattr”是一個可能的解決方案,但我想說在你的類中添加一個get
函數會使這一切更具可讀性和可維護性:
class Word:
def __init__(self, original, translation):
self.original = original
self.translation = translation
def get(self, translation):
return self.translation if translation else self.original
words = [Word("hello", "hallo"), Word("world", "Welt")]
for w in words:
print(w.get(False), w.get(True))
輸出:
hello hallo
world Welt
