Managing Sessions
Notes for Java programmers:
Unlike the Wolfram Language, Java is a compiled language and does not allow the kind of interactive coding and testing described here.
% stands for the most recent result; %n stands for the result Out[n].
Notes for Python programmers:
% in the Wolfram Language is similar to using % or %% in IPython, but IPython must be installed separately from default Python. Additionally, you can immediately compute with and manipulate %n inside other pieces of code. This cannot be done in IPython.
Use CMD+L to copy down the most recent input to the current input.
End a line with ; to make it print no output:
Notes for Python programmers:
In addition to terminating lines, semicolons in the Wolfram Language suppress output display.
% still works:
Use Short to get a short summary of output:
Use //function to apply a function at the end:
If you need to abort a computation, choose the Abort Evaluation menu item, or press CMD+. (Mac) or ALT+. (other).
