获取Python错误“from：无法读取/ var / mail / Bio”(Getting Python error “from: can't read /var/mail/Bio”)

 我正在运行（生物）python脚本，导致以下错误： 
 
from: can't read /var/mail/Bio
 
 看到我的脚本没有任何东西与邮件，我不明白为什么我的脚本看/ var / mail。 
 
 这里似乎是什么问题？ 我怀疑这将有助于脚本似乎不是问题，但这是我的脚本无论如何： 
 
from Bio import SeqIO
from Bio.SeqUtils import ProtParam

handle = open("examplefasta.fasta") 
for record in SeqIO.parse(handle, "fasta"): 
    seq = str(record.seq)
    X = ProtParam.ProteinAnalysis(seq)
    print X.count_amino_acids() 
    print X.get_amino_acids_percent() 
    print X.molecular_weight() 
    print X.aromaticity() 
    print X.instability_index() 
    print X.flexibility() 
    print X.isoelectric_point() 
    print X.secondary_structure_fraction()
 
 这里有什么问题？ 不好的python设置？ 我真的不认为这是脚本。 

I am running a (bio)python script which results in the following error:
 
from: can't read /var/mail/Bio
 
seeing as my script doesn't have anything to with mail, I don't understand why my script is looking in /var/mail.
 
What seems to be the problem here? i doubt it will help as the script doesn't seem to be the problem, but here's my script anyway:
 
from Bio import SeqIO
from Bio.SeqUtils import ProtParam

handle = open("examplefasta.fasta") 
for record in SeqIO.parse(handle, "fasta"): 
    seq = str(record.seq)
    X = ProtParam.ProteinAnalysis(seq)
    print X.count_amino_acids() 
    print X.get_amino_acids_percent() 
    print X.molecular_weight() 
    print X.aromaticity() 
    print X.instability_index() 
    print X.flexibility() 
    print X.isoelectric_point() 
    print X.secondary_structure_fraction()
 
what is the problem here? bad python setup? I really don't think it's the script.
