Non-UTF-8 code starting with '\x90' in file D:\wrl\study\venv\Scripts\python.exe on line 1, but no encoding declared;

回答: 这个问题是由于文件中包含了非UTF-8编码的字符,但是没有声明编码方式导致的。要解决这个问题,可以在文件的开头添加编码声明。可以在文件的第一行添加以下内容来声明编码方式:
```python
# -*- coding: utf-8 -*-
```
这样就可以解决非UTF-8编码的问题了。希望对你有帮助。

这段代码存在一些明显的错误,如缺少冒号、引号不匹配、缩进错误等。以下是修复后的代码:
```python
import requests
from lxml import etree
import csv
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
with open('益智.csv', mode='w', encoding='utf-8-sig', newline='') as f:
csv_writer = csv.DictWriter(f, fieldnames=['游戏名称', '游戏地址'])
csv_writer.writeheader()
for i in range(1, 123):
if i == 1:
url = 'https://www.4399.com/flash_fl/51.htm'
else:
url = 'https://www.4399.com/flash_fl/more_5_{}.htm'.format(str(i))
html = requests.get(url, headers=headers).content
doc = etree.HTML(html)
name = doc.xpath('//*[contains(@class, "list") and contains(@class, "affix") and contains(@class, "cf")]/li/a/text()')
url1 = doc.xpath('//*[contains(@class, "list") and contains(@class, "affix") and contains(@class, "cf")]/li/a/@href')
for i in range(len(name)):
data = {}
data['游戏名称'] = name[i]
new_url = 'https://www.4399.com' + url1[i]
for id in new_url:
data['游戏地址'] = id
csv_writer.writerow(data)
print(data)
```
需要注意的是,这段代码仍然存在一些问题,如 URL 的构造方式不太正确,以及数据的写入可能会存在覆盖的情况。你需要进一步检查和调整代码以确保其正确性。
Microsoft::WRL::ComPtr<IDXGIOutput1> dxgiOutput1; hr = dxgi_output.Get()->QueryInterface(__uuidof(IDXGIOutput1), reinterpret_cast<void**>(dxgiOutput1.GetAddressOf()));代码意思
这段代码的作用是将一个指向IDXGIOutput接口的ComPtr对象dxgi_output转换为指向IDXGIOutput1接口的ComPtr对象dxgiOutput1。
首先,使用Get()函数获取dxgi_output对象所指向的IDXGIOutput接口指针,并将其传递给QueryInterface函数,该函数用于查询对象是否支持特定的接口。其中,__uuidof(IDXGIOutput1)用于获取IDXGIOutput1接口的GUID,而reinterpret_cast<void**>(dxgiOutput1.GetAddressOf())用于获取dxgiOutput1对象所指向的IDXGIOutput1接口指针的地址。
如果查询成功,dxgiOutput1对象将包含指向IDXGIOutput1接口的指针。如果查询失败,dxgiOutput1对象将为nullptr。需要注意的是,在使用ComPtr对象时,不需要手动释放指针,系统会自动管理内存的释放。
