我需要创建一个程序来分析文件中的文本段落然后计数:
到目前为止,我已经成功完成了前两个要点(如下所示)
fileName = open(input('Please enter the full name of the file: '), 'r')
w = [len(word) for line in fileName for word in line.rstrip().split(" ")]
total_w = len(w)
avg_w = sum(w) / total_w
print('The total number of words in this file is:', total_w)
print('The average length of the words in this file is:', avg_w)
答案 0 :(得分:1)
collections.Counter
使这一点相对简单。我使用re.findall(r'[\w]+', data)
查找单词(单词是带有字母,下划线和数字的东西)。根据需要进行调整。
import re
from collections import Counter
fn = input('Please enter the full name of the file: ')
with open(fn, 'r') as f:
words = Counter(re.findall(r'[\w]+', f.read()))
# use words = Counter(f.read().split()) if everything split by spaces
# adjust regular expression depending on whether you want or don't want
# stuff like numbers to be counted as "words"
print('Total number of words:', sum(words.values()))
# this is weighted by word occurrence, not sure whether this is correct
print('Average length of words:',
sum(len(w) * o for w, o in words.items()) / sum(words.values()))
print('Word occurrence:', words)
# this only shows letters that actually occur. If you need all letters of
# the alphabet, you have to add the rest
print('Start letter occurrence', Counter(w[0] for w in words.elements()))
