I am trying to import Bio and read an Entrez object


from Bio import Entrez
Entrez.email = "some_email@example.com"
handle = Entrez.einfo()
print(handle.read())


i'm getting this error:

---------------------------------------------------------------------------

i've tried changing my DNS to google 8 8 8 8 and 8 8 4 4 , but it didn't work. Network is working fine and i'm able to search, but this code snippet suddenly crashed from last night. also if it is important, I'm using google colab for it. also, the version of Biopython i'm working with is 1.85 and i tried different older versions, but the problem remained the same.

Any help would be appreciated
