Python shlex.split()，忽略单引号

发布于 2024-11-26 22:13:25 字数 164 浏览 0 评论 0原文

在Python中，我如何使用shlex.split()或类似的分割字符串，只保留双引号？例如，如果输入是 "hello, world" is what 'i say' 则输出将为 ["hello, world", "is", "what", "'我”，“说”]。

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'.''')

您可以使用 shlex.quotes 控制哪些字符将被视为字符串引号。您需要修改 shlex.wordchars 同样，将 ' 与 i 和 say 保留在一起。

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'"]

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'"]
