Question

How do I copy a file in Python? I couldn't find anything under os.

Answer 1

You are presumably encountering an exception and the program is exiting because of this (with a traceback). The first thing to do therefore is to catch that exception, before exiting cleanly (maybe with a message, example given).

Try something like this in your main routine:

import sys, traceback

def main():
    try:
        do main program stuff here
        ....
    except KeyboardInterrupt:
        print "Shutdown requested...exiting"
    except Exception:
        traceback.print_exc(file=sys.stdout)
    sys.exit(0)

if __name__ == "__main__":
    main()

Answer 2

copy a file in python 

from shutil  import copyfile

 copyfile(src,dst)

where src is copy the content of file name and dst is the destination location must be writable otherwise we will get error.

file handling  is the import concept of python in file handling we can do several function like creating file , reading file,updating file and deleting file and copy content file.
