正则表达式 Regular Expressions

python method

  • search
    • wordlist = [w for w in nltk.corpus.words.words(‘en‘ ) ifw.islower()]
    • print [w for w in wordlist if re.search(‘ed$‘ ,w)]
  • findall
    • word = ‘supercalifragilisticexpialidocious‘
    • print re.findall(‘[abcd]‘, word)

注意点：

word = ‘dsupercalifragilisticexpialidocious‘

print re.findall(‘[abcd]‘,word)

print re.findall(‘^[abcd]‘,word)

print re.findall(‘[^abcd]‘,word)

分别代表：

匹配abcd任意一个

在开头匹配abcd任意一个

匹配非abcd任意一个

正则表达式Regular expressions

根据某种匹配模式来寻找strings中的某些单词 举例:如果我们想要找到字符串The dog chased the cat中单词 the,我们可以使用下面的正则表达式: /the/gi 我们可以把这个正则表达式分成几段: / 是这个正则表达式的头部 the 是我们想要匹配的模式 / 是这个正则表达式的尾部 g 代表着 global(全局),意味着返回所有的匹配而不仅仅是第一个. i 代表着忽略大小写,意思是当我们寻找匹配的字符串的时候忽略掉字母的大小写.

Using Regular Expressions in Python

1. 反斜杠的困扰(The Backslash) 有时候需要匹配的文本带有'\',如'\python',因为正则表达式有些特殊字符有特殊意义,所以需要前面加上'\'来消除特殊意义,这里匹配的正则表达式是'\\python',这时候如果要编译这个正则表达式需要re.compile('\\\\python'),因为在传递字符串的时候python本身就需要用'\\'来表示'\',也就造成了反斜杠的泛滥. 使用前缀'r'可以解决这个问题:’r'之后的'\'只是这个字符本身而没有特殊意义,比如r'\n'表

Finding Comments in Source Code Using Regular Expressions

Many text editors have advanced find (and replace) features. When I’m programming, I like to use an editor with regular expression search and replace. This feature is allows one to find text based on complex patterns rather than based just on literal
