我在使用pyhon3.4运行以下代码时报错：AttributeError: '_csv.reader' object has no attribute 'next'

import  csv
import  numpy as np
with open ( 'C:/Users/Administrator/Desktop/data/titanic.csv' , 'rb' ) as csvfile:
    titanic_reader =  csv.reader(csvfile, delimiter = ',' , quotechar =  '"' )
    # Header contains feature names
    row =  titanic_reader. next ()
    feature_names =  np.array(row)

    # Load dataset, and target classes
    titanic_X, titanic_y =  [], []
    for  row in  titanic_reader:
        titanic_X.append(row)
        titanic_y.append(row[ 2 ]) #The target value is "survived"
    titanic_X =  np.array(titanic_X)
    titanic_y =  np.array(titanic_y)

解决方案：

For version 3.2 and above

Change: csv_file_object.next()

To: next(csv_file_object)

then I get another error:

_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)

Edit: Figured it out needed to change rb to rt

Finally, it works.
