Just to clarify (I thought Daniel's answer was so easy it must 
have misinterpreted the OP's request), that's a single string as 
a filename, not a list containing a filename.  I tried

   filename = 'output.txt'
   import readline
   readline.write_history_file([filename])

and got a traceback about the expected parameter type.  For 
clarity, it should have been

   readline.write_history_file(filename)

or

   readline.write_history_file('output.txt')

But otherwise, Daniel's given a dead-easy solution.
