+description: Setup and initialization guide for developing AWS CDK (Cloud Development Kit) applications in Python. This skill enables users to configure environment prerequisites, create new CDK projects, manage dependencies, and deploy to AWS.
+---
+# AWS CDK Python Setup Instructions
+
+This skill provides setup guidance for working with **AWS CDK (Cloud Development Kit)** projects using **Python**.
+
+---
+
+## Prerequisites
+
+Before starting, ensure the following tools are installed:
+
+- **Node.js** ≥ 14.15.0 — Required for the AWS CDK CLI
+- **Python** ≥ 3.7 — Used for writing CDK code
+- **AWS CLI** — Manages credentials and resources
+- **Git** — Version control and project management
+
+---
+
+## Installation Steps
+
+### 1. Install AWS CDK CLI
+```bash
+npm install -g aws-cdk
+cdk --version
+```
+
+### 2. Configure AWS Credentials
+```bash
+# Install AWS CLI (if not installed)
+brew install awscli
+
+# Configure credentials
+aws configure
+```
+Enter your AWS Access Key, Secret Access Key, default region, and output format when prompted.
+
+### 3. Create a New CDK Project
+```bash
+mkdir my-cdk-project
+cd my-cdk-project
+cdk init app --language python
+```
+
+Your project will include:
+- `app.py` — Main application entry point
+- `my_cdk_project/` — CDK stack definitions
+- `requirements.txt` — Python dependencies
+- `cdk.json` — Configuration file
+
+### 4. Set Up Python Virtual Environment
+```bash
+# macOS/Linux
+source .venv/bin/activate
+
+# Windows
+.venv\Scripts\activate
+```
+
+### 5. Install Python Dependencies
+```bash
+pip install -r requirements.txt
+```
+Primary dependencies:
+- `aws-cdk-lib` — Core CDK constructs
+- `constructs` — Base construct library
+
+---
+
+## Development Workflow
+
+### Synthesize CloudFormation Templates
+```bash
+cdk synth
+```
+Generates `cdk.out/` containing CloudFormation templates.
+
+### Deploy Stacks to AWS
+```bash
+cdk deploy
+```
+Reviews and confirms deployment to the configured AWS account.
+
+### Bootstrap (First Deployment Only)
+```bash
+cdk bootstrap
+```
+Prepares environment resources like S3 buckets for asset storage.
+
+---
+
+## Best Practices
+
+- Always activate the virtual environment before working.
+- Run `cdk diff` before deployment to preview changes.
+- Use development accounts for testing.
+- Follow Pythonic naming and directory conventions.
+- Keep `requirements.txt` pinned for consistent builds.
+
+---
+
+## Troubleshooting Tips
+
+If issues occur, check:
+
+- AWS credentials are correctly configured.
+- Default region is set properly.
+- Node.js and Python versions meet minimum requirements.
+- Run `cdk doctor` to diagnose environment issues.
