Python shell regular expression captures complex string-specific substrings

Suddenly I realized a little bit of skill, first written here, lest later forget again.

There is a string s= ' style= ' border-top:1px dotted #DDD; text-align:left;padding-left:5px; " ><a href= "' +e.url+ '" target= "_blank" I want to take ddd out of regular expressions

You can use this string with the # and before and after the DDD, as delimiters. Examples are as follows

Import re

s= "style=" border-top:1px dotted #DDD; text-align:left;padding-left:5px; " ><a href= "' +e.url+ '" target= "_blank"

Reg=r ' [#;] + ' #关键是规则

Li=re.split (Reg,s)

Print (LI)

The results of the operation are as follows:

[' style= ' border-top:1px dotted ', ' DDD ', ' text-align:left ', ' padding-left:5px ', ' ><a href= ' \ ' +e.url+\ ' "target=" _blank ']

Summary: to take out which string to look at the string before and after it is wrapped by which two characters, use these two characters as separators to separate the string
