formatting - How to set thousend separator for PostgreSQL? -

-

I want to format the long number using thousend separator. It can be done using the to_char function: 

  SELECT TO_CHAR (76543210.98, '999G999G990D00')

But when My UTF-8 encoding is done on the Polish version of PostGreySQL server windows, such that this type of selection ends: 

  Error: invalid byte sequence for encoding "UTF8": 0xa0 Hit: This error can also occur if the byte sequence does not match the encoding required by the server, which is "Closed Int   pattern  g  is defined as:  group separator (local Uses) . This selection works without error when the server is running on Linux with Polish locale. 
 
 As a solution I use the place in the format string instead of  g , but I think that should be such a way, set the thousend separator in the defined Oracle: < / P> 
  Optional session SET NLS_NUMERIC_CHARACTERS = ',';  
 
 Is such a setting available for PostgreSQL?

If you use psql , you can execute it: 

  \ pset numericlocale

example: 

  test = # create a temporary table (a numeric (20,10) ); Create a table test = Select # select random () * 1000000 to gener_series (1,3); INSERT 0 3 test = # Select from a * *; A ------------------- 287421.6944910590 140297.9311533270 887215.3805568810 (3 lines) test = # \ pset numericlocale locale Adjusted numerical output showing Test = # select a *; One -------------------- 287.421,6944910590 140.297,9311533270 887.2153805568810 (3 lines)

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).
