python - How to open local file on Jupyter?

Question

In[1]:

path='/Users/apple/Downloads/train.csv'
open(path).readline()

Out[1]:

FileNotFoundError                         Traceback (most recent call 
last)
<ipython-input-7-7fad5faebc9b> in <module>()
----> 1 open(path).readline()

FileNotFoundError: [Errno 2] No such file or directory: 
'/Users/apple/Downloads/train.csv'

I'm confused a lot.I thought this code is exactly similar with many tutorials, and I'm sure I have this file in the right path, but why does it not works?

Answer 1

Many tutorials said that we should change Jupyter's workflow, but I didn't get it.

Finally, I find an easy way: Just drags file to this part.
