Python中要统计txt文件字数可以rstrip函数和len函数进行。
如下统计白夜行.txt的字数：
file_name = '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 白夜行.txt has about 487761 words.
