title: Bash alias --> Python 2.7 to Python 3.3
body: <p>I am trying to make Python 3.4.2 the default in Linux (currently it is 2.7.6). I am not very knowledgeable on this stuff, but I have read in several places online that you can simply put an alias in the <code>~/.bashrc</code> or <code>~/.bash_aliases</code> file like this:</p>
  
  <pre><code>alias python='python3'
  </code></pre>
  
  <p>I don't have either the <code>~/.bashrc</code> or <code>~/.bash_aliases</code> file . . . I am assuming you can just create them. I have done that, but the alias doesn't seem to be working. Am I missing something? Do you need the shebang at the beginning of the file? I have tried it both ways. </p>
  
  <p>Thanks for any help you can give! </p>
