推荐答案

pd.read_csv 接受路径或类似文件的对象.您正在传递文本本身，它试图将其作为文件名读取.您可以只传递 URL(尽管 get 不是一个很好的变量名称..)

pd.read_csv accepts a path or a filelike object. You're passing the text itself, and it's trying to read that as a filename. You can just pass the URL (although get isn't a great variable name..)

In [102]: df = pd.read_csv(get, skiprows=17, header=None)

In [103]: df.head()
Out[103]: 
            0        1        2        3        4        5
0  1413811859  98.3800  98.5000  98.3100  98.4800  1348400

2  1413811977  98.4250  98.5400  98.3800  98.4700   900000
