Pythonista already includes Sympy by default (for both Python 2 and 3), so you usually don't need to install it yourself. The version that comes with Pythonista is 0.7.4.1, which is a bit old, so if you need features or fixes from newer versions, you do need to install the current version manually.

As for installing Sympy (and other pure Python libraries) manually, you cannot use the setup.py or other installation script that comes with the library. These setup scripts assume that you're using a normal Python installation on a normal system, and don't work in Pythonista's environment. Instead, you should try Stash's pip command - it can install most pure Python packages from PyPI without any extra work.

If that doesn't work for some reason, you need to manually download the source code (which you probably did already to get the install script) and move/copy the package folder or module file into site-packages. In the case of Sympy, that is the sympy folder in the source .tar.gz.

thanks for the snapshot.
I dont have this line between.
only the extended keyboard and then the keyboard.
I thought the snippets button was combined with the "extended keyboard"?

but your tip show me the right direction!
general->keyboard->"predictive" was disabled!

I enabled it and now I can see the snippet button.

thanks to all for the great support :)

Personally, I think it would be so nice to have Pythonista on Mac OS. But I could image a lot would not like the idea of it because of cross platform issues. I see a day when we can run iOS apps under MacOS. This is the most likely way we will see Pythonista on MacOs in my opinion

@cook Cool, tomorrow!
