One more thing I would like to say about this is:
I am using 4 times urllib for calling same weblinks for different
purposes....Will this cause problem??? If yes how to solve this issue?
params1 = {'from':'PDB_ID', 'to':'ACC', 'format':'tab',
'query':session.pdbid.strip()}
data1 = urllib.urlencode(params1)
request2 = urllib2.Request('http://www.uniprot.org/mapping/', data1)
response2 = urllib2.urlopen(request2)
uniprotid = response2.read()
params = {'from':'ID', 'to':'MEROPS_ID', 'format':'tab', 'query':uniprotid3}
data = urllib.urlencode(params)
request1 = urllib2.Request('http://www.uniprot.org/mapping/', data)
response = urllib2.urlopen(request1)
params3 = {'from':'ID', 'to':'P_ENTREZGENEID', 'format':'tab',
'query':uniprotid3}
coexdata = urllib.urlencode(params3)
coexrequest = urllib2.Request('http://www.uniprot.org/mapping/',
coexdata)
coexresponse = urllib2.urlopen(coexrequest)
params4 = {'from':'ID', 'to':'P_ENTREZGENEID', 'format':'tab', 'query':mmpn}
data6 = urllib.urlencode(params4)
requestmmpn = urllib2.Request('http://www.uniprot.org/mapping/', data6)
responsemmpn = urllib2.urlopen(requestmmpn)
Thanks
