Search for words from a list in a Python string

There is a list of words, such as:

animalslist=['кот', 'собака', 'олень', 'тюлень']

600+ words long

There is a string entered by the user in the form: 

message='Какой либо текст олень какой либо текст'

What is the most effective way to find out if a string contains words from the list

The length of the string is not known in advance

animalslist = ['кот', 'собака', 'олень', 'тюлень']
message = 'Какой либо текст олень какой либо кот текст олень'.split()
sm = set(message)

# ['олень', 'кот']
print([a for a in sm if a in animalslist])

# ['кот=1', 'олень=2']
print([f'{a}={c}' for a, c in ([a, message.count(a)] for a in animalslist if a in sm) if c])

It should be a little faster (if the time in your case can be taken as an efficiency criterion) to work when so (cool option from vadim vaduxa):

animalslist = ['кот', 'собака', 'олень', 'тюлень']
message = 'Какой либо текст олень какой либо кот текст олень'.split()
sm = set(message)

print([f'{word} == {message.count(word)}' for word in animalslist if word in sm])
# ['кот == 1', 'олень == 2']
