problems about generating station.xml file

Dear obspy users,

I am trying to test a simple obspy-python script in order to generate a station.xml file ("test_manual_STATS.xml"). The scripts runs smoothly except the last line of it where it tries to write the variable "manu_stat_xml" into a file named test_manual_STATS.xml.

I pasted the error message below. Has there anyone experienced such problem before for those stations that do not belong to IRIS/ORFEUS database.
I appreciate any tip in fixing this problem. Note that the simple script I use is in the attachment.



Here is the error message:

Hi Gizem,

I’ve made a few edits to your script to get it to work (Attached). I added the “site” and “creation_date” attributes for the station, as well as the “source” attribute to the inventory.
