可以通过调用Bing Search API（v7）中的“q”查询参数来获取特色片段。以下是使用Bing搜索API（v7）和Python从Bing Web搜索中获取特色片段的示例代码：

import requests
import json

# Replace with your own subscription key and endpoint.
subscription_key = 'INSERT_SUBSCRIPTION_KEY_HERE'
endpoint = 'https://api.cognitive.microsoft.com/bing/v7.0/search'

# Define a query. In this example, the query searches for "what is the capital of France".
query = "what is the capital of France"

# Define the parameters for the request.
params = {
    'q': query,
    'mkt': 'en-US',
    'count': 1,
    'offset': 0,
    'answerCount': 1,
    'responseFilter': 'Answer',
    'textDecorations': False,
    'textFormat': 'Raw'
}

# Define the headers.
headers = {
    'Ocp-Apim-Subscription-Key': subscription_key,
}

# Send the request and get the response.
response = requests.get(endpoint, headers=headers, params=params)
response.raise_for_status()

# Extract the answer from the JSON response.
search_results = response.json()
answer = search_results['answers'][0]['value']

# Print the answer.
print('Answer: ' + answer)

这个例子返回的结果是一个特色片段，其中包含问题的答案，如“巴黎”。

请注意，要成功获取特色片段，必须使用“responseFilter”查询参数并将其设置为“Answer”（默认值为“WebPages”）。
