如何使用Python语言中的MapReduce来计算一个单词序列在文件中出现的次数？

from functools import reduce

def map_func(file_path):
    with open(file_path, 'r') as file:
        words = file.read().split()
        return [(word, 1) for word in words]

def reduce_func(word, counts):
    return word, reduce(lambda x, y: x + y, counts)

def word_count(file_path):
    # Map阶段
    mapped_data = map_func(file_path)

    # Reduce阶段
    reduced_data = {}
    for word, count in mapped_data:
        if word in reduced_data:
            reduced_data[word].append(count)
        else:
            reduced_data[word] = [count]

    result = []
    for word, counts in reduced_data.items():
        result.append(reduce_func(word, counts))

    return result

file_path = 'path/to/your/file.txt'
result = word_count(file_path)
print(result)
