python - OSError with Pybluez librairy -


i make bluetooth communication between laptop bluetooth dongle , windows 7, , raspberry pi 3.

i found on internet tutorials use pybluez librairy doesn't work me.

find below code server part : 

import bluetooth  host = "" port = 12  hostaddr = (host, port)  def setupserver():     server_socket=bluetooth.bluetoothsocket( bluetooth.rfcomm )     print("socket created.")     server_socket.bind(hostaddr)     server_socket.listen(1)     print("socket bind complete")      client_sock, client_info = server_socket.accept()     print("accepted connection " , client_info)      try:         while true:             data = client_sock.recv(1024)             if len(data) == 0: break             print("received [%s]" %data)     except ioerror:         pass      print("disconnected")  client_sock.close() server_socket.close() print("all done")

setupserver()

this output : 

socket created. traceback (most recent call last):   file "path_to_file\server.py", line 33, in <module> setupserver()   file "path_to_file\server.py", line 12, in setupserver server_socket.bind(hostaddr)   file "c:\python34\lib\site-packages\bluetooth\msbt.py", line 60, in bind bt.bind (self._sockfd, addr, port) oserror

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.

everyone! i'm trying deal eclipse rcp 3.x application. i've read lot of articles dependency injection in rcp e4 applications. can use di in rcp 3.x apps? i found perfect link di in e4. idea how use in rcp 3.x app? first of all, i'm interested in own objects injection (btw, how add own object application context?). best regards in 3.x code can ieclipsecontext necessary use contextinjectionfactory using ieclipsecontext workbenchcontext = platformui.getworkbench().getservice(ieclipsecontext.class); to workbench context. in view or editor can current part context using: ieclipsecontext partcontext = getsite().getservice(ieclipsecontext.class);
