The Main approach for checking elements of a list in a string is : <\/p>\n

s=\"\"'<a href=\"https:\/\/ertfwetwer\" target=\"_blank\">[Nerve Center]<\/a>'''\nmy_list=['href','a']\n\n   def checker(mylist, my_string)\n     new = list()\n\n     for i in mylist:\n        if i in my_string: # if elements is in string (you can check only special elements )\n            print i ,'is in string'\n            new.append(i) #storing result to new list \n\n   checker (my_list, s)\n<\/code><\/pre>\n
output :  <\/p>\n
href is in string\na is in string\n<\/code><\/pre>\n
But because you say I have long string from page source, and I want to see if .jpg or .png or .swf or .wbm or…… is inside if it is I want to store it in some var as str<\/em><\/p>\n
So you want use regex to your code for finding all .jpg or more foramtting in your long string ! let’s assume you have     <\/p>\n
s=\"\"'<a href=\"https:\/\/ertfwetwer\" target=\"_blank\">[Nerve Center]   \nmyname.jpg another.pdf mynext.xvf <\/a>'''\n<\/code><\/pre>\n
so you want to check .jpg<\/code> and another formated   <\/p>\n
my_list=['.jpg','.pdf']\n\nfor i in my_list:\n if i in s:\n  print i ,'is in string'\n<\/code><\/pre>\n
You can also find their name :    <\/p>\n
import re\ns=\"\"'<a next.pdf href=\"https:\/\/ertfwetwer\" target=\"_blank\">[Nerve Center] myfile.jpg another.pdf <\/a>'''\n\n re.findall(r'([^\\s]+).jpg|([^\\s]+).pdf',s)\n<\/code><\/pre>\n
output:   <\/p>\n
[('myfile', ''), ('', 'another')]\n<\/code><\/pre>\n
Or even   <\/p>\n
for i in  re.findall(r'([^\\s]+).jpg|([^\\s]+).pdf',s):\n    for j in i:\n        print j.strip(' ')\n\n\n\nnext\nmyfile\nanother\n<\/code><\/pre>\n<\/p><\/div>\n
