使用PYthon Spyders时出现了IOError，求问大神们该如何解决

Question

下面是错误提示
In [5]: runfile('/home/johnsnow/.spyder2/temp.py', wdir='/home/johnsnow/.spyder2')

Traceback (most recent call last):

File "", line 1, in

runfile('/home/johnsnow/.spyder2/temp.py', wdir='/home/johnsnow/.spyder2')

csv.writer(open(train_csv, 'w+'), lineterminator='\n').writerows([header[:-1]] + trn)

IOError: [Errno 13] Permission denied: '/media/johnsnow/train.csv'
出错那一行的源代码：csv.writer(open(train_csv,'w+'),lineterminator='\n').writerows([header[:-1]]) +trn)

Answer 1

 train.csv  与        train_csv 检查文件路径是否对，直接把这行代码拿出来测试。                           如果以上都对，还报错，可能是编码错误比如，你的train.csv 是unicode编码，你读的时候用的utf 编码，第一种方法，打开用Excel 进行另存为，改编码，第二种方法wb+
