Can not copy file on web page

Question

I have a python script on web page that should open one "gnuplot.gp" file and copy its content to my "final.gp" But it does not work. I have all things set up right.

Code:

file = open('gnuplot.gp','r')
plot = file.read()
file.close()


file = open('final.gp','w+')
file.write('%s' %plot)
file.close()

Can you just use [`shutil.copyfile()`](https://docs.python.org/2/library/shutil.html)? — Alex A., May 20 '15 at 18:09
at a guess that user does not have permission to create a file wherever you are running this ... — Joran Beasley, May 20 '15 at 18:09
Something to do with the fact file contains binary data? Why not just `file.write(plot)` ? — Eugene Sh., May 20 '15 at 18:12
What does "it does not work" mean? Do you get an error message? — kdopen, May 20 '15 at 18:14
I edited it to file.write(plot) my bad sorry :D But it still not working... I also set chmod of both files to 777, script too. CGI scripts are also enabled. I don't know what to do :/ - I need to do some substitution so thats why I save it to the variable for a while. — Michal Ziman, May 20 '15 at 18:17
"is not working" is possibly the most useless description of a problem. Please describe exactly in which way it "doesn't work". — bruno desthuilliers, May 20 '15 at 18:21
Works for me. Must be permissions or something like Joran mentioned — Wyrmwood, May 20 '15 at 18:22
I know that it is bad description but I do not have acces to error log... It should work but "final.gp" is still empty.. after i run the script... — Michal Ziman, May 20 '15 at 18:22

There is two things to try. One, is this (which is not a very reliable method due to file size issues);

file = open('gnuplot.gp','r')
plot = file.read()
file.close()


file = open('final.gp','w')
file.write(plot)
file.close()

Or, the other is, as others suggested, shutil.

import shutil
shutil.copyfile('gnuplot.gp','final.gp')

Of course, this is all assuming you have permissions. If you get [Access Denied], you'll either need to delete final.gp, and then copy, and/or make sure the destination directory or gnuplot.gp is not read only. If you get an empty file after trying the first method, that is because python can't handle many file types, so shutil would be the way to go.
