此处有公共属性列表:http://doc.qt.io/qt-5/qkeyevent.html
我尝试访问它们:
def add(x,y):
return x + y
我可以访问 Keys.onPressed: {
console.log("matches: ", event.matches("="));
console.log("text: ", event.text());
console.log("native modifiers: ", event.nativeModifiers());
console.log("native scan code: ", event.nativeScanCode());
console.log("native virtual key: ", event.nativeVirtualKey());
}
属性,但不能访问其他属性。
matches
为什么?
答案 0 :(得分:2)
因为您可以通过函数调用来访问属性。
只需使用def predict_retweets(dataset):
tfidf = TfidfVectorizer(tokenizer=identity_tokenizer, stop_words='english', lowercase=False)
keyword_response = tfidf.fit_transform(dataset['text']).toarray()
X = keyword_response
y = dataset['retweet_count']
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=0)
regressor = LinearRegression()
regressor.fit(X_train, y_train)
y_pred = regressor.predict(X_test)
df = pd.DataFrame({'Actual': y_test, 'Predicted': y_pred})
print(df)
return None
。
