如何返回包含短语的元组列表，以及该短语出现的次数？

def find_phrases(text, phrases):
    result = []
    phrase_count = {}

    for phrase in phrases:
        count = text.count(phrase)
        if count > 0:
            result.append((phrase, count))
            phrase_count[phrase] = count

    return result, phrase_count

text = "This is a sample text. Sample text is used for testing purposes."
phrases = ["sample text", "testing purposes", "not found"]

result, phrase_count = find_phrases(text, phrases)

print("Result:")
for phrase, count in result:
    print(f"Phrase: {phrase}, Count: {count}")

print("\nPhrase Count:")
for phrase, count in phrase_count.items():
    print(f"Phrase: {phrase}, Count: {count}")

Result:
Phrase: sample text, Count: 2
Phrase: testing purposes, Count: 1

Phrase Count:
Phrase: sample text, Count: 2
Phrase: testing purposes, Count: 1
