count = input("Enter total number of names:")
namelist = []
while num <= count:
    print "please enter name %d:" %num
    name = raw_input()
    if "," in name and name.index(",") != 0 and name.index(",") != len(name) - 1:
        namelist.append(name)
        num +=1
    else:
        print "wrong format...should be Last,First."
        errcount +=1
        print "Enter  %d error number of names " %errcount
print sorted(namelist)
