A python REPL but with an entire file. Type python expressions and evaluate them in real time.
I personally use it for symbolic algebra using sympy.
I use pysandbox primarily in the terminal using the pysandbox helper script.
You'll need the following installed:
- python (
pythonneeds to be in your path, if your distribution haspython3in the path, edit it inwatch.py) - neovim (If you wish to use a different editor, change the editor variable in
pysandbox) - tmux
- Any python dependencies imported in
pysandbox.py
Type ./pysandbox to start a pysandbox tmux session. You can now
edit main.py in the left pane, in the right pane all variables and expressions
will be live updated whenever you save the file.
Feel free to modify pysandbox.py with whatever imports or functions you find useful.
Create a filed named main.py in your editor that imports from pysandbox.py, for example:
from pysandbox import *
# For demonstration purposes
x = 2
y = 3
x + yRun python watch.py to see the output. All variables and expressions
will be live updated whenever you save the main.py file.
The idea is to have a python script (watch.py) that constantly watches the main.py file for updates.
When the file is updated, we transform the file by adding pysandbox_out calls
after each expression and assignment AST node which will print out the value in a pretty format.
