Python 浙江高考英语完型词频统计 字典

前言

好久没更新了。这段时间忙完期末又开始忙期中了……

python小白，老师布置的作业是多练习列表，字典，元组和集合。

于是乎，我照着书用字典实现了中英文词频统计。下面这个代码是我自由发挥的浙江高考英语完型词频统计。不过，统计出来的词都好简单哦哈哈哈~

第一次用计算机来解决我实际生活中的小问题，开心，纪念下。

等我会做网页了把txt文件po上来，有空我也会迭代新版本，欢迎提出优化意见。

注意点

1. 比较粗糙，无法排除很多简单的词，只能自己去筛选
2. 打印的是前800个，词频最少是2次
3. 文档里若中英文混合，则需把中文手动去除
4. txt文件要和py文件在同一个文件夹，且txt文件的命名注意：不要手动加txt的后缀，会报错

    txt = txt.lower()
    for ch in '——0123456789!\'"#$%&()*+,-./:;<=>?@[\\]^_`{|}~':
        txt = txt.replace(ch, " ")      #将文本中特殊字符替换为空格
    return txt
zjgkTxt = getText()
words = zjgkTxt.split()
counts = {}
for word in words:
    counts[word] = counts.get(word,0) + 1
for word in excludes:
    del(counts[word])
items = list(counts.items())
items.sort(key=lambda x:x[1], reverse=True)
for i in range(800):
    word, count = items[i]
    print("{0:<800}{1:>5}".format(word, count))

拓展

强推Python入门书《Python语言程序设计基础 第2版》，主要是有实例，边学边实践，非常有意思！
