使用python统计txt文件字数

刚看完白夜行，想看看究竟有多少字，正好看到书里有异常处理的作业，就顺便一起写了。

file_name = '東野圭吾－白夜行.txt'

try:
    with open(file_name, encoding='utf8') as file_obj:
    #由于书名不是英文，要加上 encoding='utf8'
        contents = file_obj.read()
except FileNotFoundError:
    msg = 'Sorry, the file' + file_name + ' does not exist.'
    print(msg)
else:
    words = contents.rstrip()
    num_words = len(words)
    print('The file ' + file_name + ' has about ' + str(num_words) + ' words.')

结果：

The file 東野圭吾－白夜行.txt has about 487761 words.

哇，我真是太不容易了，看的都快吐了好么。。。
