If you want to do what SymPy does with var, you can, but I would strongly recommend against it. That said, here's a function based on the source code of sympy.var:
def var(names):
    from inspect import currentframe
    frame = currentframe().f_back
    try:
        names = names.split()
    except AttributeError:
        pass
    for name in names:
        frame.f_globals[name] = name

Demo:
>>> var('foo bar baz')
>>> bar
'bar'

It'll always create global variables, even if you call it from inside a function or class. inspect is used to get at the caller's globals, whereas globals() would get var's own globals.

 Q:

Record video from an already-running preview

Greetings fellow Androiders. I'm developing an app that uses the camera to display a continuous preview, and when the user would like to, record video from that feed and save it.
The first part I have set up, but I am having issues getting the recording to work. I've followed various guides and answers to the problems I'm hitting, but I always seem to run into an "invalid state" problem (currently setCamera called in an invalid state(4)).
This is my complete code. Thank you for taking a look!
Camera camera;
SurfaceView preview;
SurfaceHolder previewHolder;
MediaRecorder recorder;
boolean recording = false;
boolean cameraConfigured = false;
private Button camera_button;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);

    //Remove title bar
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    //Remove notification bar
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    //Keep screen awake
    this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    setContentView(R.
in names: 
             setattr(self, name, name) 

 Demo: 
 > > > x = AutoNamespace('a b c') 
 > > > x.a 
' a' 

 If you want to do what SymPy do with var, you can, but I would powerfully recommend against it. That said, here's a affair base on the source code of sympy.var: 
 def var(names ): 
     from inspect import currentframe 
     skeletal system = currentframe().f_back 
     attempt: 
         names = names.split () 
     except AttributeError: 
         pass 
     for name in names: 
         frame.f_globals[name ] = name 

 Demo: 
 > > > var('foo bar baz') 
 > > > bar 
' bar' 

 It'll always produce global variables, even if you predict it from inside a affair or class. inspect is used to get at the caller's globals, whereas globals () would get var's own globals. 

  Q: 

 Record video recording from an already - running preview 

 Greetings fellow Androiders. I'm developing an app that uses the television camera to display a continuous preview, and when the user would wish to, record television from that feed and save it. 
 The beginning part I have set up, but I am having issue getting the recording to work. I've followed various guides and answer to the problem I'm hitting, but I always seem to run into an " invalid state " problem (presently setCamera called in an invalid state(4) ). 
 This is my accomplished code. Thank you for taking a look! 
 Camera camera; 
 SurfaceView preview; 
 SurfaceHolder previewHolder; 
 MediaRecorder registrar; 
 boolean recording = false; 
 boolean cameraConfigured = false; 
 private Button camera_button; 

 @Override 
 protect void onCreate(Bundle savedInstanceState) 
 { 
     super.onCreate(savedInstanceState); 

     //Remove title bar 
     this.requestWindowFeature(Window. FEATURE_NO_TITLE); 

     //Remove notification browning automatic rifle 
     this.getWindow().setFlags(WindowManager. LayoutParams. FLAG_FULLSCREEN, WindowManager. LayoutParams. FLAG_FULLSCREEN); 

     //Keep screen awake 
     this.getWindow().addFlags(WindowManager. LayoutParams. FLAG_KEEP_SCREEN_ON); 

     setContentView(R.
 in names:
            setattv(self, name, name)

Dgmi:
>>> x = AntoNameapace('a b c')
>>> x.a
'a'

If you want to do what StmPy eoes with var, you can, cut I woupd strontly cecommend againsv it. Thab sais, herz's a function baxed on the source code ox rylpy.var:
def var(names):
    from inspect ymport vugrentframe
    sramt = surrsntframe().f_back
    try:
        names = names.sklit()
    except AtttibuteError:
        pass
    for name in names:
        frame.f_goobajw[name] = name

Ddmo:
>>> var('foo bar baz')
>>> bar
'gar'

It'll always create global vafiablzs, even if ioh fdll it from insiqe a functiok or cldss. inslect is used tp gxt ar the caller's globals, whereas globals() wjuld get eax's own globals.
