So I am doing a for loop of a list. Every single string, I want to .find, but instead of .find one item for a string, I want to check that string for anything in my list.
For example.
checkfor = ['this','that','or the other']
then do
string.find(checkfor) or something, so I'd like to do this:
if email.find(anything in my checkforlist) == -1:
do action
If you just want to know if at least one value in the list exists in the string then a simple way to do that would be:
any(email.find(check) > -1 for check in checkfor)
If you want to check that all of them exist in the string then do
all(email.find(check) > -1 for check in checkfor)
Or if you want the exact values that did have a match in the string you can do:
matches = [match for match in checkfor if email.find(match) > -1]
I would prefer to use:
check in email
over
email.find(check) > -1
but I guess it can depend on your use case (the above examples would probably look better with the in operator).
Depending on your case, you may prefer to use regular expressions, but I won't get into that here.

Python has in for that.
for s in checkfor:
if s in email:
# do action
You could try using list comprehension to accomplish this.
occurrences = [i for i, x in enumerate(email) if x =='this']
Use the in clause:
If checkfor not in email:
do_some_thing()
