prompter: I have a codebase in Python. There are many classes and complex hierarchies. I need a tool that can automatically generate a dependency graph for me. For example, it should generate an image that shows using arrows what classes are connected via composition or inheritance. Could you please recommend a few tools for that?

assistant: Sure! Here are a few tools that you can use to automatically generate a dependency graph for your Python codebase:

1. Pyreverse - Pyreverse is a tool that generates UML-style class diagrams and package dependency graphs from Python code. It is part of the PyDev plugin for Eclipse and can also be used as a standalone tool.

2. Graphviz - Graphviz is a powerful open-source graph visualization tool that can be used to generate a variety of diagrams, including class diagrams and package dependency graphs. You can use Graphviz to visualize your Python code by first generating a dot file using a tool like Pyreverse, and then using Graphviz to generate an image from the dot file.

3. Gephi - Gephi is an open-source network visualization tool that can be used to generate class diagrams and package dependency graphs. Gephi provides a number of layout algorithms to arrange nodes and edges, making it possible to generate clear and readable diagrams from large codebases.

4. PlantUML - PlantUML is a tool that generates UML diagrams from a simple text language. It can be used to generate class diagrams and package dependency graphs, and provides a number of customization options to control the appearance of the diagrams.

These are just a few examples of the many tools available for generating dependency graphs for Python code. Each tool has its own strengths and weaknesses, so it's best to experiment with a few of them to see which one works best for your codebase.

prompter: I don't think PlantUML can generate automatically.

assistant: You're right, my apologies for the mistake. PlantUML is not a tool for automatic generation of dependency graphs. It is a text-based language for creating UML diagrams, but it requires manual input of the class relationships. Thank you for pointing that out.

assistant: You are correct that PlantUML is a bit different from the other tools I mentioned in that it requires you to write the diagram in a text format. If you need automatic generation you can try using the other tools I mentioned such as Pyreverse, Graphviz or Gephi, which are capable of generating dependency graphs and class diagrams automatically from Python code. These tools should be able to meet your needs in visualizing the structure and dependencies of your Python codebase.

assistant: You can use the command `pyreverse` which is included with the `pylint` package:

```shell
$ pip install pylint
$ pyreverse [options] <packages>
```

For example, this command will output a pdf class diagram called `classes.pdf` for a python package called `example`:

```shell
$ pyreverse -o pdf example
```

More documentation on `pyreverse` can be found here: https://pylint.readthedocs.io/en/latest/pyreverse.html

prompter: Besides `pyreverse`, what other tools does the `pylint` package contain?

assistant: In addition to pyreverse, pylint package contains several other tools, such as:
-`pylint`
-`pyreverse`
-`symilar`
-`pylint-gui`
-`epylint`
-`pylint-brain`

assistant: The other package that ```pylint``` contains is ```symilar```, which is a duplicate code finder.
