title: /usr/bin/env python opens up python, but ./blabla.py does not execute
body: <p>python blabla.py will execute. But ./blabla.py gives me an error of "no such file or directory" on CentOS6.3.</p>
  
  <p>/usr/bin/env python does open up python properly.</p>
  
  <p>I am new to linux and really would like to get this working. Could someone help?</p>
  
  <p>Thanks in advance!</p>

  <p>Note: thanks to all the fast replies!
  I did have the #!/usr/bin/env python line at the beginning.</p>
  
  <p>which python gives /usr/bin/python as an output.</p>
  
  <p>And the chmod +x was done as well.</p>
  
  <p>The exact error was "no such file or directory" for ./blabla.py, but python blabla.py runs fine.</p>
