Question

I have searched Google  Stack Overflow and my Python users guide and have not found a simple  workable answer for the question   I created a file c  goat txt on a Windows 7 x64 machine and am attempting to print  test  to the file  I have tried the following based on examples provided on StackOverflow   At this point I don t want to use the log module since I don t understand from the documentation of to create a simple log based upon a binary condition   Print is simple however how to redirect the output is not obvious   A simple  clear example that I can enter into my interperter is the most helpful   Also  any suggestions for informational sites are appreciated  NOT pydocs    import sys print  test   file open  C   goat txt    w     fails print arg  file open  fname    w      above based upon this print gt  gt destination  arg  print gt  gt  C   goat txt   test    Fails based upon the above

A slightly hackier way  that is different than the answers above  which are all valid  would be to just direct the output into a file via console   So imagine you had main py  if True      print  hello world  else      print  goodbye world    You can do  python main py  gt  gt  text log   and then text log will get all of the output   This is handy if you already have a bunch of print statements and don t want to individually change them  to print to a specific file  Just do it at the upper level and direct all prints to a file  only drawback is that you can only print to a single destination

Building on previous answers  I think it s a perfect use case for doing it  simple  context manager style   import sys  class StdoutRedirection         Standard output redirection context manager         def   init   self  path           self  path   path      def   enter   self           sys stdout   open self  path  mode  w           return self      def   exit   self  exc type  exc val  exc tb           sys stdout close           sys stdout   sys   stdout     and then   with StdoutRedirection  path to file        print  Hello world     Also it would be really easy to add some functionality to StdoutRedirection class  e g  a method that lets you change the path
