You can use the re module to do a regular expression search.

import re

s = 'abcNumber:"1234"ID:XXXYYY END'

pat = re.compile(r'''
  ID     # a literal ID
  .{3}   # any three characters
  YYY    # a literal YYY''', re.X)
if re.search(pat, s):
    print("Yep!")

Typical use case for regular expressions:

import re

s = 'abcNumber:"1234"ID:XXXYYY END'

match = re.search(r"ID:(.{3})YYY", s)  # capture the group of 3 anthings between your markers
if match:
    print(f"found: {match.group(1)}")

# found: XXX
