How to embed the output of a Subprocess embedded in curses window using Python

0 votes
802 views

Does any one have a good solution for how to embed the output of a subprocess (ex. subprocess.Popen("htop", stdout=subprocess.PIPE)) into an ncurses window? So for example, the terminal window is broken up into quadrants and the top right has htop running inside. I'd imagine this would involve some kind of terminal emulation as the dimensions of the window would need to be queried by htop.

In this script i am calling the other script named abc.py which is located on the desktop with 64 and abc as its arguments I am getting the following error

File "/usr/lib64/python2.6/subprocess.py", line 589, in __init__

Limit Lines of Output using python

I've got a simple script that counts the number of words in a data set (it's more complicated than that, but that's one of the functions), but there are so many words that the output is too much to see in the command prompt window. What I'd like to be able to do is incorporate the "More..." feature that help libraries have, but I have no idea how to do it. I also don't know if I'm asking the question correctly because a Google search yielding nothing.

How to quickly search over a large number of files using python?

I have about 500 search queries, and about 52000 files in which I have to find all matches for each of the 500 queries.

How should I approach this? Seems like the straightforward way to do it would be to loop through each of the files and go line by line comparing all the terms to the query, but this seems like it would take too long.

Can someone give me a suggestion as to how to minimize the search time?

Find the max number of elements in lists as value in a dictionary using Python?

I want to find the maximal number of elements contained in a nested dictionary, e.g.

data = {
 'violations':
 {
 'col1': {'err': [elem1, elem2, elem3]},
 'col2': {'err': [elem1, elem2]}
 }
 }

so to find the maximal number of elements in the lists for key 'err' in key 'col1' and 'col2'. Also key 'violations' may contain many keys (e.g. 'col1' , 'col2', 'col3' etc), so what's the best way to do this (using a loop)?

max = 0for col in data.violations:
 if max < len(data.violations.col.err):
 max = len(data.violations.col.err)
...
