您可以在写入 CSS 文件之前cssText使用该函数解码in ASCIIsheet.cssText.decode('ascii')

# -*- coding: utf-8 -*-

import cssutils

css = '''/* a comment */

    .chat {

        background: #fff;

        color: white;

    }

    .chat-history {

        height: 100px;

        padding: 8px 24px;

        overflow-y: scroll;

    }

#live-chat header {

    background: #293239;

    border-radius: 5px 5px 0 0;

    color: #fff;

    cursor: pointer;

    padding: 16px 24px;

}

'''

sheet = cssutils.parseString(css)

for rule in sheet:

    if rule.type == rule.STYLE_RULE:

        # find property

        for property in rule.style:

            if property.name == 'color':

                property.value = 'green'

                property.priority = 'IMPORTANT'

                break

        # or simply:

        rule.style['margin'] = '01.0eM' # or: ('1em', 'important')

# cssutils.ser.prefs.resolveVariables == True since 0.9.7b2

cssTextDecoded = sheet.cssText.decode('ascii')

print(cssTextDecoded)

with open("hello.css", 'w') as f:

    f.write(cssTextDecoded)
