Modified your code as mentioned below:

  with open(r'annual_budget.txt', 'r') as f:
     reader = csv.reader(f)
     headers = reader.next() # this will yield first row i.e columns if python 3: Use next(reader) instead of reader.next()
     for line in reader:
         rowdata = map(float, line)
         data.extend(rowdata)
     print(sum(data)/len(data))
