使用Python和PyQt5/PySide6制作浏览器。我实现了一个广告拦截器，它使用列表来阻止广告以选项卡的方式打开。
```python
class WebPage(QWebEnginePage):
	adblocker = filter(open(os.path.join("build files", "adlist.txt"), encoding="utf8"))
	def __init__(self, parent=None):
		super().__init__(parent)
	def acceptNavigationRequest(self, url, _type, isMainFrame):
		urlString = url.toString()
		resp = False
		resp = WebPage.adblocker.match(url.toString())
		if resp:
			print("阻止URL --- " + url.toString())
			return False
		else:
			print("类型", _type)
			return True
		return QWebEnginePage.acceptNavigationRequest(self, url, _type, isMainFrame)

I am making a browser using python and PyQt5/PySide6. I implemented an adblock which uses a list to block ads from opening as tabs.
`

adblocker = filter(open(os.path.join("build files", "adlist.txt"), encoding="utf8"))
def __init__(self, parent=None):
	super().__init__(parent)
def acceptNavigationRequest(self, url,  _type, isMainFrame):
	urlString = url.toString()
	resp = False
	resp = WebPage.adblocker.match(url.toString())
	if resp:
		print("Blocking url --- "+url.toString())
		return False
	else: 
		print("TYPE", _type)
		return True
	return QWebEnginePage.acceptNavigationRequest(self, url,  _type, isMainFrame)

I tried to fix this, but to no avail.
I am expecting the code to raise no errors. The code is supposed to prevent the user from opening ads.

你需要将筛选功能添加到filter()函数中：
```python
adblocker = filter(filter_by, open(os.path.join("build files", "adlist.txt"), encoding="utf8"))
```
其中，filter_by是一个接受数组中的元素并返回布尔值的函数。示例：
```python
array = [1, 2, 3, 4, 54, -5, -1]
def positive(x):
    return x >= 0
filter_ed = filter(positive, array)  # 返回 [1, 2, 3, 4, 54]
```

you need to add the filtering function to filter()
    adblocker = filter(filter_by, open(os.path.join(&quot;build files&quot;, &quot;adlist.txt&quot;), encoding=&quot;utf8&quot;))
where filter_by is a function that takes an element of the giving array and returns a bool
example: 
    array = [1, 2, 3, 4, 54, -5, -1]
    def positive(x):
        return x&gt;=0
    filter_ed = filter(positive, array) # return [1, 2, 3, 4, 54]
