ipython - Problems writing to Excel in pandas -

-

have following annoying problem ipython script using to_excel function in pandas: @ end of script want write results excel file. if include path e.g "~/", script breaks down enclosed error messages. if input file name script runs , produce new file in current folder. bug or doing wrong? code follows:

path=dir+file_name print "writing %s " % path opt_design.to_excel(path, sheet_name='sheet1',index=false) print "finished!"``

the runtime error is:

--------------------------------------------------------------------------- ioerror                                   traceback (most recent call last) <ipython-input-1-b9e6707b5b6c> in <module>()  43 path=dir+file_name  44 print "writing %s " % path ---> 45 opt_design.to_excel(path, sheet_name='sheet1',index=false)  46 print "finished!"  47

python doesn't expand home directory you. have couple of options:

  1. os.path.expanduser(the_path)
  2. os.path.join(os.environ.get('home'), the_path)

here's example

in [17]: os.path.expanduser('~/a_path_wth_tilde') out[17]: '/home/phillip/a_path_wth_tilde'
