Here’s a solution using regex if that’s what you really need. I search to see if any of your 3 substrings are present inside any given string from the list. Using https://docs.python.org/3/library/re.html as the Python regex library.
import re
for word in wordList:
m = re.search('.*(ra|dec|lat).*', word)
if m:
<youve matched here>
