I would like to count how many times a list of words (file1) appears in another list of words (file2)

with open("corpus.txt", "r") as f1, open("lexico.txt", "r") as f2:
    file1 = f1.read()
    file2 = f2.read()

    corpus1 = file1.split(" ")

    for word in file2:
        print(word, corpus1.count(word))

Corpus.txt file (file2)

You can do the following:

count = {}

with open('corpus.txt') as f1, open('lexico.txt') as f2:
    corpus = f1.read().split() # texto
    for word in f2: # palavras a quantificar no texto
        w_strp = word.strip() # retirar quebras de linha
        if w_strp != '' and w_strp not in count: # se ja a adicionamos nao vale a pena faze-lo outra vez
            count[w_strp] = corpus.count(w_strp)
print(count) # {'mas': 2, 'é': 2, 'luz': 4}

Or in this case:

count = {}

with open('corpus.txt') as f1, open('lexico.txt') as f2:
    corpus = f1.read().split()
    lexico = set(word.strip() for word in f2 if word.strip() != '') # set() para evitar palavras repetidas

count = {l_word: corpus.count(l_word) for l_word in lexico}
print(count) # {'mas': 2, 'é': 2, 'luz': 4}

If you are sure that no repeated words in lexico.txt , you can only:

...
lexico = [word.strip() for word in f2 if word.strip() != '']
...

Or until:

count = {}

with open('temp/corpus.txt') as f1, open('temp/lexico.txt') as f2:
    corpus = f1.read().split()
    count = {l_word: corpus.count(l_word) for l_word in (word.strip() for word in f2 if word.strip() != '')}

print(count) # {'mas': 2, 'é': 2, 'luz': 4}
