The following code returns an empty record:

handle = Entrez.efetch(db="Taxonomy", id="158330", retmode="xml") #From biopython tutorial
records = Entrez.read(handle) #Record is empty

Answer 1

同じことを試したところ、返されるレコードは空ではありません。

In [20]: handle = Entrez.efetch(db="Taxonomy", id="158330", retmode="xml")

In [21]: records = Entrez.read(handle)

In [22]: records
