Alright, basically I have a list of words in a file and I load each word

I assume you meant 'list' ?

Then basically the question is how do I
check if the input word matches multiple words in the list.
Say someone input "test", how could I check if that word matches these list
of words:
test
testing
tested
Out of the list of
Hello
blah
example
test
ested
tested
testing
I want it to loop then check if the input word I used starts any of the
words in the list so if I typed 'tes'
Then:
test
testing
testing
<OP>
I assume you meant:
test
tested
testing
</OP>
would be appended to a new array.

Using a regexp for this is total overkill. But please at least use the
proper regexp, and use re.compile correctly:
exp = re.compile(r'^tes')
found = [word for word in lis if exp.match(word)]
But you just don't need a regexp for this - str.startswith is your friend:
words = ['Hello', 'blah', 'example', 'test', 'ested', 'tested', 'testing']
found = [word for word in words if word.starswith('tes')]
assert found == ['test', 'tested', 'testing']
