Python shlex.split(), ignore single quotes

How, in Python, can I use shlex.split() or similar to split strings, preserving only double quotes? Fo开发者_高级运维r example, if the input is "hello, world" is what 'i say' then the output would be ["hello, world", "is", "what", "'i", "say'"].


import shlex

def newSplit(value):
    lex = shlex.shlex(value)
    lex.quotes = '"'
    lex.whitespace_split = True
    lex.commenters = ''
    return list(lex)

print newSplit('''This string has "some double quotes" and 'some single quotes'.''')


You can use shlex.quotes to control which characters will be considered string quotes. You'll need to modify shlex.wordchars as well, to keep the ' with the i and the say.

import shlex

input = '"hello, world" is what \'i say\''
lexer = shlex.shlex(input)
lexer.quotes = '"'
lexer.wordchars += '\''

output = list(lexer)
# ['"hello, world"', 'is', 'what', "'i", "say'"]
