Ending a while loop when it encounters a string containing 'end' (python) [duplicate]

Question

Here, I have a list of ints, strings, and lists:

from types import *
import re
l1 = [3, 'c', 'thisshouldendloop', 'e', ['h', 2, 'p', 'g'], 7, 4, 5]

I want a while loop which prints each list element and stops when it encounters any string containing 'end'. Before stopping, it should print the string containing 'end', as well. Here's what I have:

length = len(l1)
index = 0
while index < length:
  for s in l1:
      if (type(s) == 'int'):
          print(s)
          index += 1
      elif (type(s) == 'string'):
          if re.search('end', s):
              print(s)
              # attempts to end while loop by making index > length
              index += (length * 2)
          else:
              print(s)
              index += 1
      else:
          print(s)
          index += 1

Output:

3
c
thisshouldendloop
e
['h', 2, 'p', 'g']
7
4
5

What output should look like:

3
c
thisshouldendloop
