Revision history [back]

Sage is based on Interactive Python. Therefore, every feature in IPython works in SageMath. For example, one feature is automatic-parentheses-and-quotes.

So, if you are too lazy to write parenthesis and commas, then you can turn on the autocall magic and use it by starting the line by /:

sage: %autocall 1
Automatic calling is: Smart
sage: f(x,y,z) = x + y^2 + z^3
sage: /f x+1 y+2 z+3                  # no parenthesis, no comma!
(z + 3)^3 + (y + 2)^2 + x + 1

There is also the auto-quoting which can be used if you are too lazy to quote strings. It may be activated by starting the line with a comma:

sage: ,print aujourd'hui                # no parenthesis, no comma, no quotes "" !
aujourd'hui
