Keyword search in string

I'm making simple keyword recognition program where I have a txt file and every word is in new line. I open as a list and then I check for every keyword in sentence I will later open from database.

So far I get this error: 

TypeError: 'in <string>' requires string as left operand, not list

I get it both needs to be string-string or list-list. I experimented and tried to convert the sentence into list - program returned nothing.

Any suggestions how to make this work, or suggestions how to change things to make it correct?

results = []
with open('words.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip())


#print results

all_text = 'vistumšākā zaudēt zilumi nāve'

#all_texts = all_text.split()

for word in results:
    if results in all_texts:
        x += 1

print x

You've got a simple typo here. You're trying to check each word from your words.txt file, but you're using results in your if statement. Hence the error; Python's saying "I expected this variable to contain a string, but it was actually a list." Change your second for loop: 

for word in results:
    if word in all_texts:
        x += 1

I've renamed your variables to be more descriptive in the full program below: 

word_list = []
with open('words.txt') as inputfile:
    for line in inputfile:
        word_list.append(line.strip())

source_text = 'vistumšākā zaudēt zilumi nāve'
source_words = source_text.split()
count = 0    

for word in word_list:
    if word in source_words:
        count += 1

print count
