How to create a full python app with bazel

creating a full python application using bazel involves several steps. bazel is a build and test tool that is particularly good at managing dependencies and building large projects. here’s a step-by-step tutorial on how to set up a simple python application with bazel.

### prerequisites

3. **basic knowledge of python and command line**: familiarity with python programming and command-line operations is helpful.

### project structure

let's create a simple python application that takes user input and prints a greeting. the project structure will look like this:

### step 1: create your project directory

create a directory for your project:

### step 2: create a simple python application

### step 3: create a requirements file (optional)

### step 4: create the build file

now, create a `build` file in the project directory. this file contains the build rules for bazel. add the following content to `build`:

### step 5: initialize bazel

to use bazel with python, you may need to configure bazel for python support. if you are using external dependencies, you can use the `rules_python` library to manage python dependencies.

1. **create a workspace file**: in the project directory, create a `workspace` file (can be empty or can contain dependencies):



2. **add rules for python**: you need to set up `rules_python` in your `workspace` file. add the following content:

### step 6: build and run your application
