Simple question about tuple of scala -

-

I'm new to Scala, and what I'm learning is taple .

>

I can define a tuple as the following, and get the items: 

  val tuple = ("Mike", 40, "New York ") Println (" name: "+ tuple .0)  
        
 How to get the length of tubal?  
  •  Is Tupal Unstable? Can I modify my items?  
  •  Is there any other useful operation that we can do on tuple?   
     Thanks in advance!   <
     
     
     1]  Tupel.product error  
     
     2] No. 
     
     3] Some interesting operations you can do on Tupla: (a small REPL session) 
     
      scala> Val x = (3, "hello") x: (int, java.lang.String) = (3, hello) scale & gt; X.swap res0: (java.lang.String, Int) = (Hello, 3) Skal & gt; X.toString res1: java.lang.String = (3, hello) scale & gt; Val y = (3, "hello") y: (int, java.lang.String) = (3, hello) scale & gt; X == y res2: Boolean = true scale & gt; X.productPrefix res3: java.lang.String = Tuple2 scala & gt; Val xi = x.productIterator xi: Itater [any] = empty eater scale & gt; While (xi.hasNext) println (xi.next) Hello 3

    Obfuscating Python code? -

    I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
