Python code editor

How to use it

Editor — open text mode and edit code manually.
Build — convert code into blocks on the workspace.
Close — exit the editor without building blocks.
Code from blocks and from the editor is the same: after building, blocks are replaced with the new program.

Editor features

Syntax highlighting for keywords, strings, numbers, and comments.
Tab — indent (4 spaces); Shift+Tab — outdent.
Enter after a line with : — automatic indent inside a block.
Backspace at the start of a line — remove the entire indent.

What you can write

Variables, print, input, arithmetic, and comparisons.
if / elif / else, for and while loops.
break, continue, lists, strings, and their methods.
import math, import random, functions from these modules.

Limitations

Only features that have blocks in the builder are supported.
Not allowed: custom functions (def), classes, from … import, complex one-line expressions.
If Build shows an error — simplify the code or assemble the program from blocks.
