Question

我正在使用此（https://github.com/thibauts/duckduckgo）模块来搜索duckduckgo搜索结果：

>>> import duckduckgo
>>> for links in duckduckgo.search('Yellow Chris Martin',max_results=20):
...     print links

在输出中我得到搜索结果，似乎有重复4次相同的链接

输出：

如何修复此问题并获得与使用搜索引擎时相同的结果。

Answer 1

您可以使用将duckduckgo对象转换为列表，然后使用set（）：

count = 10
while( set(list(duckduckgo.search('Yellow Chris Martin',max_results=count)) ) < some_val ):
    count = count + 1

for links in set(list(duckduckgo.search('Yellow Chris Martin',max_results=count)) :
    print links

如何获得独特的搜索结果？
