Here's a summary of the ways to call external programs and the advantages and disadvantages of each: os.system("some_command with args")  passes the command and arguments to your system's shell. This is nice because you can actually run multiple commands at once in this manner and set up pipes and input/output redirection. For example, os.system("some_command < input_file | another_command > output_file") However, while this is convenient, you have to manually handle the escaping of shell characters such as spaces, etc. On the other hand, this also lets you run commands which are simply shell commands and not actually external programs. see documentation stream = os.popen("some_command with args")  will do the same thing as  os.system  except that it gives you a file-like object that you can use to access standard input/output for that process. There are 3 other variants of popen that all handle the i/o slightly differently. If you pa...

1. Install MongoDB : Download tgz or zip file from MongoDB website   Extract tgz or zip file in home directory eg : /Users/userName/mongodb_x86_64-3.0.0 Add path of mongoDB directory in PATH 2. Run MongoDB server : Create a directory for primary DB path. /Users/userName/mongodb_x86_64-3.0.0/data/db Run Command /Users/userName/mongodb_x86_64-3.0.0/bin/mongod --dbpath /Users/userName/mongodb_x86_64-3.0.0/data/db  --bind_ip 0.0.0.0 -v 3.

Step 1 : Install Eclipse Step 2 : Install PyDev Here is the easiest way of drag-n-drop : http://marketplace.eclipse.org/content/pydev-python-ide-eclipse Step 3 : Configure Python Interpreter Path to MayaPy's python interpreter : /Applications/Autodesk/maya2014/Maya.app/Contents/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python Extras : 1. For Autocompletion, add following line in "Forced Builtins" : maya.cmds,maya.mel,maya.standalone,maya.app,maya.OpenMaya,maya.OpenMayaAnim,maya.OpenMayaCloth,maya.OpenMayaFX,maya.OpenMayaMPx,maya.OpenMayaRender,maya.OpenMayaUI which will add following libraries : maya.cmds maya.mel maya.standalone maya.app maya.OpenMaya maya.OpenMayaAnim maya.OpenMayaCloth maya.OpenMayaFX maya.OpenMayaMPx maya.OpenMayaRender maya.OpenMayaUI Another Resource :  http://sourceforge.net/p/pydev/discussion/293649/thread/fb1b2e45

Unity Editor Scripting : If you ever have to create an instance (in hierarchy) from an .fbx file and a prefab from an instance, you can use following commands. 1 .fbx to instance      :  PrefabUtility . InstantiatePrefab 2 instance to .prefab :  PrefabUtility . CreatePrefab Creating AnimatorController file :  AssetDatabase . CreateAsset  

Conditional Operator / Ternary Operator : condition ? true_expression : false_expression; bool x = condition ? true : false; eg : string   result  = (percentage  >= 36)  ?  "pass"  :  "fail" ; -------------------------------------------------------- NullCoalesce (??) int totalMarks = marks ?? 0 ; The  ??  operator is called the null-coalescing operator. It returns the left-hand operand if the operand is not null; otherwise it returns the right hand operand. eg:  int ? x = null ; int y = x ?? -1; int? is a shorthand for Nullable, which itself is shorthand of Nullable. eg Nullable a = null; A nullable type can represent the correct range of values for its underlying value type, plus a additional null value. --------------------------------------------------------

           Great trick for optimization so that code doesn't have to count size of array/list again and again.    for  ( int   i  =  0 ,  count  =  objectList . Count ;  i  <  count ;  i ++)             {                 .......  =  objectList [ i ];                  if  ( .... )                 {                     ........                 }             }
