os.path.basename(file).rsplit(".", 1)[0]

对于我来说，这是某种残酷。要获得升降索的名称，你必须经历这个......

Python 中是否有一个选项可以充分获取文件名，而无需分割...

Arduino 1.9.2，ESP32-WROOM 常规版。我买了它并且正在做通常的固件（闪烁 LED）。它编译、上传，在 99% 时停止并给出超时终端错误。我应该怎么办？在其他设备上一切正常并闪烁。告诉我，怎么了？

我正在尝试创建一个片段。其中一行包含电话号码模式的参数 =“+?[0-9\s-()]+”。如何在代码片段中正确编写，以便稍后调用代码片段时正确显示

"fieldset-div": {
        // "scope": "html",
        "prefix": "fieldset-div+",
        "body": [
            "<fieldset class=\"\">\n\t\n<legend class=\"\"></legend>\n\t\n<div class=\"\">\n\t\n<div class=\"\">\n\t<input id=\"\" class=\"\" type=\"text\" name=\"\" placeholder=\"First name\" required>\n\t</div>\n\t\n<div class=\"\">\n\t<input id=\"\" class=\"\" type=\"text\" name=\"\" placeholder=\"First name\" required>\n\t</div>\n\t\n<div class=\"\">\n\t<input id=\"\" class=\"\" type=\"tel\" name=\"\" pattern="\+?[0-9\s\-\(\)]+" placeholder=\"Phone number\">\n\t</div>\n\t\n<div class=\"\">\n\t<input id=\"\" class=\"\" type=\"email\" name=\"\" placeholder=\"Email address\" required>\n\t</div>\n\t\n</div>\n\t\n<div class=\"\">\n\t<textarea id=\"\" class=\"\" name=\"\" placeholder=\"Message\" autocomplete=\"off\"></textarea>\n\t</div>\n\t\n</fieldset>"

如果每个模型都在单独的文件中，谁能告诉我如何使用 SQLAlchemy 关系？例子：

# ./models/user.py
class UserModel(Base):
    __tablename__ = 'users'
    id: Mapped[int] = mapped_column(primary_key=True)
    characters: Mapped[list['CharacterModel']] = relationship(back_populates='user')

# ./models/character.py
class CharacterModel(Base):
    __tablename__ = 'characters'
    id: Mapped[int] = mapped_column(primary_key=True)
    user_id: Mapped[int] = mapped_column(ForeignKey('users.id', ondelete='CASCADE'))
    characters: Mapped['UserModel'] = relationship(back_populates='characters')

# ./models/__init__.py
from . import user, character

创建用户时出错：

sqlalchemy.exc.InvalidRequestError: When initializing mapper Mapper[UserModel(users)], expression 'CharacterModel' failed to locate a name ('CharacterModel'). If this is a class name, consider adding this relationship() to the <class 'python.database.models.user.UserModel'> class after both dependent classes have been defined.

我在任何地方都找不到信息，并且在使用模型的示例中它总是在一个文件中。如果有任何信息，我将不胜感激。
