Stdout Redirect From Jupyter Notebook Is Landing In The Terminal

So I was trying to redirect stdout for a some of the cells in my Jupyter Notebook to a file with this and then cancel it with this for the rest of the cells. The output from the fi

Solution 1:

The only explanation I see is that sys.stdout is notsys.__stdout__ but a rerouted/modified file object in order to be able to put data in cells (your comment indicates that it's a ipykernel.iostream.OutStream instance).

So instead of resetting to sys.__stdout__, you should store the reference of sys.stdout:

import sys
old_stdout = sys.stdout
sys.stdout = open('stdout.txt', 'w')
...
sys.stdout = old_stdout

Note that this method also works with a standard terminal.
