使用文档上下文管理器，如果文档不存在，会有什么行为？

Question

python cloudant库有一个上下文管理器来简化对文档的处理：

# Upon entry into the document context, fetches the document from the
# remote database, if it exists. Upon exit from the context, saves the
# document to the remote database with changes made within the context. 
with Document(database, 'julia006') as document:
    # The document is fetched from the remote database
    # Changes are made locally
    document['name'] = 'Julia'
    document['age'] = 6
    # The document is saved to the remote database

如果远程文档不存在，该行为是什么？文档是否设置为None，或者是否引发异常？你知道吗

Answer 1

如果远程数据库中不存在该文档，则会在远程数据库中为您创建该文档。你知道吗
