Answer 1

e = "/some/path" in h5File

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

Answer 2

After checking the documentation at group docs. I assume you can use the keys method of the group object to check before usage:

# check if node exists
# first assume it doesn't exist
e = False
node = "/some/path"
if node in h5file.keys():
    h5File[node]
    e = True

Answer 3

You can also simply use require_group() method for groups. H5py Docs.
