interpreter

This module provides classes to open a Python interactive interpreter in a page. It is used by the console and the editor of the site brython.info.

Classes

Interpreter(element=None, title="Interactive Interpreter", globals=None, locals=None, rows=30, cols=84, default_css=True)

  • if element is None, the interpreter is opened in a new dialog box (cf. module browser.widgets.dialog).

    Otherwise, element can be an existing TEXTAREA in the page page, or the attribute id of an existing TEXTAREA.
  • if element is None, title is the title of the dialog box
  • dictionaries globals and locals are the environment where the interpreter commands are executed (by default, empty dictionaries)
  • rows and cols are the TEXTAREA dimensions
  • default_css specifies if the CSS stylesheet provided by the module should be used. If the value is False, the styles defined in the HTML page are used (cf. "CSS style" below)

from interpreter import Interpreter

Interpreter()

Inspector(title="Frames inspector", rows=30, cols=84, default_css=True)
Opens a dialog box with an interactive interpreter running in the program execution frames. This can be used for debugging purposes.

Note that opening an inspector does not block program execution, but the namespaces used in the inspector represent the state of the frames when it was opened.

For instance, in this example, the value of y in frame f is 8, not 9:

from interpreter import Inspector

def f(x):
  y = 8
  Inspector()
  y = 9

f(5)

CSS style

If an interpreter is opened in an existing TEXTAREA, the HTML stylesheet is used.

Otherwise, if argument default_css is True (default), the following stylesheet in inserted in the page:

.brython-interpreter {
    background-color: #000;
    color: #fff;
    font-family: consolas, courier;
}

Pour personnaliser l'apparence des boites, il faut passer comme argument

To customize the interpreter look, pass default_css=False and redefine the CSS class brython-interpreter. The most straightforward is to copy-paste the stylesheet above and edit it.
