用于匹配两个或三个空格的Python正则表达式

Question

I'm trying to match the following text with a regex in Python 2.7

SUBCASE   8
SUBCASE   9
SUBCASE  10
SUBCASE  11

The number of spaces between "subcase" and the number drops from 3 to 2. I'm trying to use this regex in Python:

(SUBCASE)[\\s+]([0-9]+)

Where am I going wrong? Shouldn't the \\s+ mean "catch any white spaces more than one"?

Answer 1

You'll want:

SUBCASE\s+([0-9]+)

or

SUBCASE\s+(\d+)

Putting \\s+ inside of [...] means, that you want precisely one symbol that either is a whitespace character, or a plus.

Answer 2

(SUBCASE)\s+([0-9]+) 

你使用了[\\ s +]来做一个空格或+符号的字符匹配
