body: <p>I'm  making an application that supports multi language. And I am using <code>gettext</code> and <code>locale</code> to solve this issue. </p>
  
  <p>How to set LANG variable in Windows? In Linux and Unix-like systems it's just as simple as</p>
  
  <p><code>$ LANG=en_US python appname.py</code></p>

  <p><code>C:\&gt;SET LANG=en_US python appname.py</code> </p>
  
  <p>or </p>
  
  <p><code>C:\&gt;SET LANG=en_US</code> </p>
  
  <p><code>C:\&gt;python appname.py</code></p>
