将文件中的单词读入字典 [英] Read words from file into dictionary

问题描述

因此，在我们的作业中，我的教授希望我们逐行阅读文本文件，然后逐字阅读，然后创建一个字典，计算出每个单词出现的频率.这是我现在拥有的:

so in our assignment my professor would like us to read in a text file line by line, then word by word, then create a dictionary counting the frequency of each word appearing. Here's what I have for now:

wordcount = {}
with open('/Users/user/Desktop/Text.txt', 'r', encoding='utf-8') as f:
    for line in f:
        for word in line.split():
            line = line.lower()
            word = word.strip(string.punctuation + string.digits)
            if word:
                wordcount[word] = line.count(word)
    return wordcount

发生的是，我的词典告诉我每个单词在特定行中出现了多少，而当某些单词多次出现在整个文本中时，我剩下的多数为1.我如何才能使字典来计算整个文本中的单词，而不仅仅是一行?

What happens is that my dictionary tells me how many of each word appears in a particular line, leaving me with mostly 1s when some words show up in the entire text many times. How can I get my dictionary to count words from the entire text, not just a line?

推荐答案

问题是您每次都要重置它，解决方法很简单:

The problem is you are resetting it every time, the fix is quite simple:

wordcount = {}
with open('/Users/user/Desktop/Text.txt', 'r', encoding='utf-8') as f:
    for line in f:
        for word in line.split():
            line = line.lower()
            word = word.strip(string.punctuation + string.digits)
            if word:
                if word in wordcount:
                    wordcount[word] += line.count(word)
                else:
                    wordcount[word] = line.count(word)
    return wordcount
