I'm using Python in GAE and I noticed that if I use TAB when writing the code it generates an error when trying to run it. So, I had to use Notepad++ checking where TAB characters were and substitute them by blank spaces.
I'd like to know a better way to indent the code... does anyone have already had this problem?
Most language-aware editors allow you to specify that you want tabs to be converted automatically to e.g. 2 or 3 spaces as you type. Notepad++ almost certainly supports this so have a look in the preferences/settings. Alternatively you could use a free Python editor like Pyscripter or Spyder. If your editor has Python-specific settings, it should recognise the current tab level and indent each new line automatically.
