Python uml class diagram

What’s the best way to generate a UML diagram from Python source code?

Generating UML diagrams from Python source code is a useful way to visualize software design and architecture. There are several tools available for generating UML diagrams, but in this guide, we will focus on using the `pyreverse` tool provided by `pylint`.

Installing Pylint

Before we can use `pyreverse`, we need to install `pylint`. We can do this using pip, the Python package manager. Open a terminal and run the following command:

Generating UML diagrams with Pyreverse

Once we have installed `pylint`, we can use the `pyreverse` command to generate UML diagrams. The syntax of the `pyreverse` command is as follows:

where « is the name of the Python module for which we want to generate the UML diagram.

For example, let’s say we have a Python module named `example.py` that we want to generate a UML diagram for. We can run the following command:

This will generate a file named `classes.dot` in the current directory, which contains the UML diagram in the DOT language.

Converting DOT to an Image

To view the UML diagram, we need to convert the DOT file to an image format such as PNG or SVG. We can use the `dot` command provided by Graphviz to do this. If you don’t have Graphviz installed, you can download it from the Graphviz website.

To convert the `classes.dot` file to a PNG image, we can run the following command:

dot -Tpng classes.dot -o classes.png 

This will generate a PNG image file named `classes.png` in the current directory.

Example

Let’s look at an example. Suppose we have a Python module named `example.py`, which contains the following code:

class Animal: def __init__(self, name, species): self.name = name self.species = species def make_sound(self): pass class Dog(Animal): def __init__(self, name): super().__init__(name, "Dog") def make_sound(self): print("Woof!") class Cat(Animal): def __init__(self, name): super().__init__(name, "Cat") def make_sound(self): print("Meow!") 

To generate a UML diagram for this module, we can run the following commands:

pyreverse example.py dot -Tpng classes.dot -o classes.png 

This will generate the following UML diagram:

Conclusion

In this guide, we have seen how to generate UML diagrams from Python source code using the `pyreverse` tool provided by `pylint`. We have also seen how to convert the DOT file generated by `pyreverse` to an image format using the `dot` command provided by Graphviz. By using these tools, we can easily visualize the architecture and design of our Python projects.

Getting UML diagrams in pycharm for the same program, but pyreverse is showing parsing error. Why is it so ?

Getting UML diagrams in pycharm for the same program, but pyreverse is showing parsing error. Why is it so ?

I had something similar happen to me recently. I found out that something was broken in pylint v2.5.0. The latest v2.6.0 fixed things for me. If not installing via pip, ensure your astroid package is updated.

Thank You so much. Will update.

do we have options like extracting data from excel and converted into UML. if yes kindly update
