Read files with only specific names from Amazon S3

There are several ways to do this in Python. For example, checking if 'stringA' is in 'stringB':

list1=['test-eob/PROCESSED_BY/FILE_JSON/222-Account.json',
'test-eob/PROCESSED_BY/FILE_JSON/1212121-Account.json',
'test-eob/PROCESSED_BY/FILE_JSON/122-multi.json',
'test-eob/PROCESSED_BY/FILE_JSON/qwqwq-Account.json',
'test-eob/PROCESSED_BY/FILE_JSON/wqwqw-multi.json',]

for i in list1:
    if 'Account' in i:
        print (i)
    else:
        pass

You can make use of a regex that matches your pattern from the list of objects.

import re

MATCH = "FILE_JSON/.*?Account.json"

full_list = [
  "test-eob/PROCESSED_BY/FILE_JSON/222-Account.json",
  "test-eob/PROCESSED_BY/FILE_JSON/1212121-Account.json",
  "test-eob/PROCESSED_BY/FILE_JSON/122-multi.json",
  "test-eob/PROCESSED_BY/FILE_JSON/qwqwq-Account.json",
  "test-eob/PROCESSED_BY/FILE_JSON/wqwqw-multi.json"
]

for item in full_list:
  if re.search(MATCH, item):
    print(item)
