Python for iOS is based on Python 2.7 instead of the intentionally backward-incompatible next-generation Python 3. This is a good thing for old-school Python developers like me who never migrated to Python 3. Note that the Python 2.7 fork is still maintained as a viable programming language version. Python for iOS provides the familiar command-line interactive interpreter, which looks and feels the same as you might remember from using it on some *nix server in the past. The app augments the iPad's soft keyboard with a scrollable row of mini-keys for characters that are used often. The mini-keys are small but useable.
