redirect output of ipython script into a csv or text file like sqlplus spool

问题

I try to redirect the output of my script to a file. I don't want to do something like

python myscript.py > xy.out

as a lot of the variable is being stored in my ipython environment and I like to carry it over.

I try to follow this link

IPython: redirecting output of a Python script to a file (like bash >)

however, when I try to do

with redirect_output("my_output.txt"):
    %run my_script.py

It gives the error

---> 10         self.sys_stdout = sys.stdout
NameError: global name 'sys' is not defined

There is a similar solution to copy the output of a ipython shell to a file but It says my cell its not defined

https://www.quora.com/How-do-I-export-the-output-of-the-IPython-command-to-a-text-file-or-a-CSV-file

Is there a easier way or build in feature with ipython that does that ?? e.g.

In oracle sqlplus there is a spool command e.g.

spool /tmp/abc
select * from table_x;
spool off

now the sql statement output is in /tmp/abc

Is such a equivalent for ipython ??

回答1:

Greeting. I end up using this solution:

%%capture var2
%run -I script2

import sys
orig_stdout = sys.stdout
f = file('out5.txt', 'w')
sys.stdout = f 
print var2
stdout = orig_stdout
f.close()

It is not very handy but it works!
