Simplest way to eval python code

[Yehonathan Sharvit]

What is the simplest way to eval python code in the browser with Skulpt?

I'd like to evaluate subsequent python code snippets and I need the function defined in a snippet to be accessible by subsequent snippets.

For instance:

snippet 1:

foo = lambda n: n + 2

print(foo(3))

snippet 2:

print(foo(5))

Could anybody help me on this issue?

Skulpt is not designed to remember things from previous runs.  If you want it to know about foo in another run then you will need to include that in the code you hand over to importMainWithBody.

Is there a way to set a global variable to some global object and get its value in subsequent runs, in the sam  browser instance?

Someone could help with this topic?

I'm looking for a way to set a global variable to some global object and get its value in subsequent runs, in the same  browser instance.

I haven't tried it using the latest version of Skulpt ... but in the older version of Skulpt (the one used on www.codeskulptor.org), anything stored in Sk.builtins is not cleared between runs and remains available during subsequent runs.

For example, if I run the following python code: 

def foo(x): return "foo"+str(x)+"bar"

Then Sk.globals['foo'] will be a reference to the JavaScript version of the foo function. If I then run (in the JavaScript console, for example) Sk.builtins.foo = Sk.globals['foo'] then in subsequent runs, foo will be a "builtin" function ... and therefore work even though it wasn't defined in the current run.

You'd have to be careful not to overwrite any of the actual "builtin" functions ... but this might be a way for your functions to remain persistent ... or to be defined "outside" the current run.

I hope that helps.
