从 Entrez 下载完整记录

问：

我无法从NCBI获得大肠杆菌基因组的数据。为此，我使用了两个文档来获取数据 http://biopython.org/DIST/docs/tutorial/Tutorial.html#sec149 http://biopython.org/DIST/docs/tutorial/Tutorial.html#sec37

所以我写了一个代码：

from Bio import Entrez
from Bio import SeqIO

Entrez.email = "may mail"

organism_id = "NC_000913"
handle = Entrez.efetch(db="nucleotide", id=organism_id, rettype="gbwithparts", retmode="text")
record = SeqIO.read(handle, "genbank")
handle.close()
genome_length = len(record.seq)

但是，我收到一个奇怪的错误。例如：

   1352     r = h.getresponse()
   1353 except:

我不知道我该如何解决这个问题？你能帮帮我吗？提前致谢。
