我需要搜索列表中的任何项是否包含特定字符串。目前我使用此代码:
mylist = ['Hometown City Heights', 'Height 6'', 'First name Mike']
item = [s for s in mylist if "First name" in s]
print item[0]
>> First name Mike
问题在于,如果我尝试搜索Height
,我得到了这个:
mylist = ['Hometown City Heights', 'Height 6'', 'First name Mike']
item = [s for s in mylist if "Height" in s]
print item[0]
>> Hometown City Heights
我只需匹配Height
元素中包含的Height 6'
,因此item [0]将是我需要的那个。最好的方法是什么?
答案 0 :(得分:1)
您可以拆分项目,然后查看:
item = [s for s in mylist if "Height" in s.split()]
演示:
>>> mylist = ['Hometown City Heights', "Height 6'"]
>>> [s for s in mylist if "Height" in s.split()]
["Height 6'"]
>>>
作为一种更通用的方法,您可以使用正则表达式搜索您的模式:
import re
[s for s in mylist if re.search(r'\b{}\b'.format(pattern),s)]
演示:
>>> pattern='First name'
>>> [s for s in mylist if re.search(r'\b{}\b'.format(pattern),s)]
['First name Mike']
