Program in Visual and Modular Blocks in Python

PyFlow is an interactive Python development tool structured in open source graphs.

With PyFlow you can create code blocks in which you can edit and run Python code, you can move and resize blocks in an infinite 2D plane. Just link the blocks to highlight dependencies, Pyflow will automatically run your blocks in the correct order.

Installation

To get PyFlow on your system you need to use pip and run the following command:

pip install --user byc-pyflow

After the installation is complete, to run PyFlow, just run:

python -m pyflow

The PyFlow window will open, click on File and then on New to create a block scheme.

PyFlow File New

Then right-click on the plane and choose the type of block: Markdown or Code .

PyFlow Code or Markdown

Example of a code block:

Example of a Markdown block:

By clicking on the triangle or square it is possible to create a node and join it to another block. See in this example, I created the variable example in one block and printed it in the other:

In this other example I created a function that prints a message and in the other node a variable with a URL and in the third node I print the message and I already open the URL in the default browser as soon as I click >> to execute the code:

Click on the image to enlarge and view the code better (it will open in a new tab of your browser).

To save your project press Ctrl + s .
