How to (using console) put results in a txt. file or get complete results from a code that has already runned

Question

i'm currently solving optimization problems with python. One problem takes about 5hrs to solve which result will appear (sadly) in console but not completely since it's a very big list. I'm wondering right now if there is anyway to get the solution of the list completely while i'm waiting for the results (i've been waiting for 4hrs. now).

If there is a way i can get the complete result in the console after the code has runned, let me know. If there is a way via console to put the results in a .txt file or any type of readable file afterwards please let me know.

If there is no solution to this problem, let me know.

Thanks alot.

You mean, the code will terminate, as in the process will be done? — juanpa.arrivillaga, Jun 20 '17 at 21:38
Yes you can put data in a text file. If you post code I can show you how to do it for your case. Side Note: WHAT on earth is taking 5 hours to run? — Easton Bornemeier, Jun 20 '17 at 21:39
I'm doing Prim's method for MTS problems with 10000 nodes and 61700+ edges. How do you do that @EastonBornemeier. — DIEGO ALFONSO ARTURO MILLARD F, Jun 20 '17 at 21:40
@EastonBornemeier optimization problems, apparently. Which doesn't sound particularly crazy. In any event, I think the issue is that they have run some script, `python optimization_script.py`, but the output is simply the result of printing a giant `list` — juanpa.arrivillaga, Jun 20 '17 at 21:41
Unfortunately, I don't think there is much you can do except wait for it to finish, and re-write the code to output to a file instead of printing to the console. Maybe you can make your terminal scroll-back unlimited? — juanpa.arrivillaga, Jun 20 '17 at 21:42

say your script is called yourscript.py and you have been running it in the console with: python yourscript.py

if you use this command:

python yourscript.py > newfile.txt

all of the output will go into newfile.txt

I mean, i do not have to import anything? – DIEGO ALFONSO ARTURO MILLARD F Jun 20 '17 at 21:43
all i have to write in console is "python "nameofthescript".py > newfile.txt"? – DIEGO ALFONSO ARTURO MILLARD F Jun 20 '17 at 21:44

exactly! if you make a little test python file that just has one line like: print("hello world") you can try running that from the console and then try running it with > newfile.txt - you'll see – perry Jun 20 '17 at 21:45
@DIEGOALFONSOARTUROMILLARDF but that is how you are *suppose to run the script*. I'm not sure you can redirect once the process is alreaady running. – juanpa.arrivillaga Jun 20 '17 at 21:45

Suppose your python file is myfile.py, in order to redirect what is printed in this file run your file as:

python myfile.py > myfile.txt

Your printed list will be printed in myfile.txt.

the txt file will be in the same folder as the script? – DIEGO ALFONSO ARTURO MILLARD F Jun 20 '17 at 21:45
Doing that you'll get your complete list at `myfile.txt`, yes. – rodgdor Jun 20 '17 at 21:45
If you run your program like `python myfile.py > myfile.txt` then yes. – rodgdor Jun 20 '17 at 21:47
thanks, ill check your answer if it works once the code is over. – DIEGO ALFONSO ARTURO MILLARD F Jun 20 '17 at 21:47
You can run a file in two ways, using its **relative path** or its **absolute path**, respectively: `python myfile.py` and `python /home/documents/myfile.py`. Supposing you are at the directory (in your console) `/home/documents/` and that `myfile.py` is there. Then by running `python myfile.py > myfile.txt` will create `myfile.txt` in the same directory. – rodgdor Jun 20 '17 at 21:52
@DIEGOALFONSOARTUROMILLARDF this isn't something you can do *after* the code is done running. You need to do this *before*. – juanpa.arrivillaga Jun 20 '17 at 21:53

pipe it into a file with the format you want for example your file name is xyz.py

In your python shell

 python xyz.py > myfile.txt

Your output will now be in myfile.txt
