python - 'tuple' object has no attribute 'rstrip' -


i got problem :

'tuple' object has no attribute 'rstrip'

my script :

def destroyvm(request,id):     conn = sqlite3.connect('testdb')     c = conn.cursor()        api = 'http://196.203.216.18:5555/client/api'     apikey = '3u7uplr4jhyezohke0jynr_icchdmuynnl0sdqmfzfgg4hgd6bjhhjcsk2k3ssxuvheleon-slrueopqzbqbva'     secret = 'ju1gqk99vpaezwwkxir97w8miptszsxwuorl6h2nkkve0ehdvbz5iqn-cxhqmhvkmolrcrhjyr4rpntqamd5ig'     cloudstack = cloudstack.client(api, apikey, secret) # ouvrir une connexion serveur/client     c.execute("select vmid vmm_vm id ="+id+";");     conn.commit()     vmid = c.fetchone()     vm = cloudstack.destroyvirtualmachine({'id':vmid})      c.execute("delete vmm_vm id = '"+id+"';")      conn.commit()      conn.close()      return render_to_response('vms.html',{'vms':vm.objects.all()})

is problem in vmid ? when fetch query enter image description here

cursor.fetchone returns sequence (a tuple case) represent row.

you need extract item tuple.

vmid = c.fetchone()[0]

or using tuple unpacking:

vmid, = c.fetchone()  # same (vmid,) = c.fetchone()
