我想删除字符串中的单词,即列表中的单词或“种子”单词,
示例:
query = "LK936033.1 Babesia assembly 454hybrid_PBjelly scaffold Contig1323 7"
seeds = ["assembly","454","scaffold","contig"]
期待结果:
"LK936033.1 Babesia 7"
我找到了一种删除这样的词的方法:
' '.join([i for i in query.split() if i not in seeds])
但此方法仅从种子列表中删除完全单词,但不删除包含种子的单词。
答案 0 :(得分:2)
你需要扩展你的考试;使用any()
function提高效率:
' '.join([i for i in query.split() if not any(w in i.lower() for w in seeds)])
any(w in i.lower() for w in seeds)
测试使用生成器表达式来测试当前单词是否包含任何种子词,小写;它只会评估找到匹配项的最小测试次数。
演示:
>>> query = "LK936033.1 Babesia assembly 454hybrid_PBjelly scaffold Contig1323 7"
>>> seeds = ["assembly","454","scaffold","contig"]
>>> ' '.join([i for i in query.split() if not any(w in i.lower() for w in seeds)])
'LK936033.1 Babesia 7'
