List comprehension and any:
[i for i in list1 if any(i for j in list2 if str(j) in i)]any to check if any element of list2 is a substring of the list1 item (__contains__) being iterated over
Example:
In [92]: list1 = ['bj-100-cy','bj-101-hd','sh-200-pd','sh-201-hp']
...: list2 = [100, 200]
...:
In [93]: [i for i in list1 if any(i for j in list2 if str(j) in i)]
Out[93]: ['bj-100-cy', 'sh-200-pd']list1 = str(list1)
list2 = str(list2)You are converting your list into a string with the above statements. So when you iterate in a for loop, you are iterating each characters, instead of each word.
So you should remove string conversion and instead do a list comprehension as follows. Also, in your outcome file instead of checking if the word in list2 is in list1, you are checking the opposite. So you got like 100 and 200 as chars which are in list 2.
list1 = ['bj-100-cy','bj-101-hd','sh-200-pd','sh-201-hp']
list2 = [100, 200]
outcome = [x for x in list1 for y in list2 if str(y) in x]Another alternative list comprehension :
>>> list1 = ['bj-100-cy','bj-101-hd','sh-200-pd','sh-201-hp']
>>> list2 = [100, 200]
>>> occur = [i for i in list1 for j in list2 if str(j) in i]
>>> occur
['bj-100-cy', 'sh-200-pd']No matter what stage you're at in your education or career, TuteeHub will help you reach the next level that you're aiming for. Simply,Choose a subject/topic and get started in self-paced practice sessions to improve your knowledge and scores.
