Question

我有这段代码

    for play_type in play_codes['general']:
        if play_type in play_tx:
            code = play_codes['general'][play_type]['code']
            break

引用字典'play_codes'（下面转载的部分）

play_codes = {
              'general':{
                         'falló en':            {'code':'',   'description':'generic out'},
                         'se ponchó':           {'code':'K',  'description':'strike out'},
                         'por base por bolas':  {'code':'BB', 'description':'walk'}
                        }
             }

循环遍历各种play_type，如果匹配则将“代码”分配给代码（基本上是if then elseif循环）

它工作得很漂亮 - 除非play_type包含utf8扩展字符，例如代字号，然后我得到：

TypeError: 'in <string>' requires string as left operand

在此之后，我要解析韩语，所以这是我需要掌握的东西！

Answer 1

此代码适用于我。请注意顶部的文件编码声明。这可能是你的问题（即它违反了ascii）。

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

play_codes = {
    'general':{
        'falló en':            {'code':'',   'description':'generic out'},
        'se ponchó':           {'code':'K',  'description':'strike out'},
        'por base por bolas':  {'code':'BB', 'description':'walk'}
    }
}

#play_tx = ('falló en', 'se ponchó', 'por base por bolas')
play_tx = "M.Brito falló en rolata al lanzador."

for play_type in play_codes['general']:
    if play_type in play_tx:
        code = play_codes['general'][play_type]['code']
        break

如果结果是问题那么你可以在这里看到更多信息 https://www.python.org/dev/peps/pep-0263/

嗯，即使我将编码设置为ascii也能正常工作。所以现在我有点困惑。发布所有代码。
