如何验证任何字符串列表是否在另一个数组中并在 Python 中附加该数组

Question

I have an array of strings in Python:

array=array(['Thisis_anapple','Thatis_acat', 'Thoseare_dogs'], dtype=object)

I want to append all the strings that have 'cat' or 'dog'. Ideal result is:

list=['Thatis_acat','Thoseare_dogs']

My code is:

list=[]
if any(x in array for x in ['cat', 'dog']):
    list=list.append(x)
print(list)

But the result is actually blank list.

Answer 1

A = ['Thisis_anapple','Thatis_acat', 'Thoseare_dogs']
L = ['cat', 'dog']
R = [entry for entry in A if any(l in entry for l in L)]
print(R)

This solution involves conditional list comprehension

It basically says make a list R, so that it includes every entry from A if any pattern from L can be found in that entry.

Answer 2

You can use re :

import re

array = ['Thisis_anapple','Thatis_acat', 'Thoseare_dogs']
words = ['cat', 'dog']
to_find = re.compile('|'.join(words))

result = list(filter(to_find.search, array))

This could be done using a list comprehension instead of using filter but it seemed more appropriate:

result = [s for s in array if to_find.search(s)]

---

Result: (same for both filter and list comp)

['Thatis_acat', 'Thoseare_dogs']
