分割()，忽略单引号

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

如何在Python中使用shlex.split()或类似于拆分字符串，只保留双引号?例如，如果输入是“hello, world”，那么输出将是[“hello, world”，“is”，“what”，“i”，“say”]。

#1

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.

您可以使用shlex。用于控制哪些字符将被视为字符串引号的引号。您需要修改shlex。还有文字游戏，以保持“我”和“说”。

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'"]
