Python正则表达式用于未公开的引号

Question

  

可能重复：
  Split a string by spaces — preserving quoted substrings — in Python

给出以下字符串：

term1 term2 "the second term has spaces" term3 bad term 4

正则表达式会给我这个列表：

["term1", "term2", "the second term has spaces", "term3", "bad", "term", "4"]

Answer 1

对于您的简单示例，这样可以正常工作：

import re
quotestring = 'term1 term2 "the second term has spaces" term3 bad term 4'
# uses a lookahead and lookbehind to check for quoted strings
stringlist = re.findall(r'((?<=\").+(?=\")|\w+)', quotestring)
print(stringlist) # works on Python 2 or 3

或者，来自链接的帖子：

import shlex
quotestring = 'term1 term2 "the second term has spaces" term3 bad term 4'
stringlist = shlex.split(quotestring)
print(stringlist)
