本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- PYTHON_DOTENV_DISABLED set to truthy values ('1', 'true', 'yes', 't', 'y') causes load_dotenv to return False and load nothing into os.environ, while dotenv_values continues to parse files
- load_dotenv with override=False (default) preserves existing os.environ keys and resolves variable expansions (${VAR}) using os.environ values rather than .env file definitions
- load_dotenv with override=True overwrites existing os.environ keys and resolves variable expansions using .env file definitions
- dotenv_values always evaluates variable expansions using file values regardless of existing os.environ definitions, diverging from load_dotenv(override=False)
- interpolate=False disables variable interpolation and preserves ${VAR} and ${VAR:-default} as raw string literals
- unset variable parameter expansion (${UNSET:-default}) evaluates to default while unset variable without default (${UNSET}) evaluates to empty string
- keys without values ('KEY=') resolve to empty string ('') whereas valueless keys ('KEY') resolve to None in dotenv_values and are skipped by load_dotenv
