def count_words(filename):#统计指定文件单词的数量
    """Count the approximate number of words in a file."""
    try:
        with open(filename, encoding='utf-8') as f:
            contents = f.read()
    except FileNotFoundError:
        pass
    else:
        words = contents.split()#以空格分隔形成列表
        num_words = len(words)#统计列表元素的个数
        print(f"The file {filename} has about {num_words} words.")

filenames = ['alice.txt', 'siddhartha.txt', 'moby_dick.txt', 'little_women.txt']
for filename in filenames:
    count_words(filename)
