python - Python中的单引号与双引号[关闭](Single quotes vs. double quotes in Python [closed])

Question

According to the documentation, they're pretty much interchangeable.

(根据文档，它们几乎可以互换。)

Is there a stylistic reason to use one over the other?

(是否有出于某种风格的原因要在一个之上使用另一个？)

Answer 1

I like to use double quotes around strings that are used for interpolation or that are natural language messages, and single quotes for small symbol-like strings, but will break the rules if the strings contain quotes, or if I forget.

(我喜欢在用于插值或自然语言消息的字符串周围使用双引号，对于像符号一样小的字符串使用单引号，但是如果字符串包含引号或我忘记了，则会违反规则。)

I use triple double quotes for docstrings and raw string literals for regular expressions even if they aren't needed.

(我对文档字符串使用三重双引号，对正则表达式使用原始字符串文字，即使不需要它们也是如此。)

For example:

(例如：)

LIGHT_MESSAGES = {
    'English': "There are %(number_of_lights)s lights.",
    'Pirate':  "Arr! Thar be %(number_of_lights)s lights."
}

def lights_message(language, number_of_lights):
    """Return a language-appropriate string reporting the light count."""
    return LIGHT_MESSAGES[language] % locals()

def is_pirate(message):
    """Return True if the given message sounds piratical."""
    return re.search(r"(?i)(arr|avast|yohoho)!", message) is not None
