- 网址观察与批量生成
-
for i in range(2,10): url='http://www.sogou.com/{}.html'.format(i) print(url)
2.英文词频统计预处理：
- 下载一首英文的歌词或文章或小说。
- 将所有大写转换为小写
- 将所有其他做分隔符（,.？！）替换为空格
- 分隔出一个一个的单词
- 并统计单词出现的次数。
-

3.文件操作：
- 同一目录、绝对路径、相对路径
-
fo=open('book.txt','r',encoding='utf8') content=fo.read() fo.close() print(content,end='')
- 凯撒密码：从文件读入密函，进行加密或解密，保存到文件。
- 词频统计：下载一首英文的歌词或文章或小说，保存为utf8文件。从文件读入文本进行处理。
