windows - Python COM object , won't save numpy array -

i have simple com object setup in python, want see inputs coming in , have them transferred array want save text file can read it.

but com object performing usual skips on numpy save command.

here code

 class pythonutilities(object): _public_methods_=['function']  # # use pythoncom.createguid() 2/1/08 # _reg_clsid_= pythoncom.createguid() _reg_desc_ = "utilities extending amibroker afl" _reg_progid_ = "example1" _readonly_attrs_ = ['revision'] _public_attrs_=['ndepvar','arraylen','probarray',                 'x_open','x_high','x_low','x_close',                 'x_volume','x_oi','log']  def function(self,inlist):     # example infinite impulse response filter amibroker docs     #     inlist=list(inlist)     a=[]     if inlist == 0:         inlist = [10,10,10,7,7,7,7]      a=np.asarray(inlist)     np.savetxt("inlint1.txt" , a, fmt='%.18e', delimiter=', ', newline='\n')      return inlist  if __name__=='__main__':     print "registering com server "     import win32com.server.register     win32com.server.register.usecommandline(pythonutilities) 

why np.savetxt not executing ??
