检查h5py中是否存在节点 [英] Check if node exists in h5py

问题描述

我想知道是否有一种简单的方法可以使用h5py检查HDF5文件中是否存在节点.

I am wondering if there is a simple way to check if a node exists within an HDF5 file using h5py.

我在文档中找不到任何内容，所以现在我正在使用异常，这很丑.

I couldn't find anything in the docs, so right now I'm using exceptions, which is ugly.

# check if node exists
# first assume it exists
e = True
try:
  h5File["/some/path"]
except KeyError:
  e = False # now we know it doesn't

添加上下文:我正在使用它来确定节点是否存在，然后再尝试创建具有相同名称的新节点.

To add context: I'm using this to determine if a node exists before trying to create a new node with the same name.

推荐答案

e = "/some/path" in h5File

做到了. Group文档中非常简短地提到了这一点.

does it. This is very briefly mentioned in the Group documentation.
