使用新的{foo='bar'，key=none}dict语法包装ast.literal的eval。
litereval的Python项目详细描述
文学评论
litereval是ast.literal_eval的包装，有新的附加{foo='bar', key=None}dict语法。
再加上一些帮助工具来深入合并字典，将python数据解析为*args和**kwargs。
可用于创建包装器命令行接口见pyppdf。
安装
需要Python3.6+
conda install -c defaults -c conda-forge litereval
或
pip install litereval
