Setting up Environment for FastAPI Python

If you are a beginner in Python and want to start learning FastAPI, you first need to set up your development environment properly. Follow these steps to get started:

Step 1: Install Python

Make sure you have Python installed on your system. You can download and install Python from the official website: https://www.python.org/downloads/

Step 2: Install FastAPI

Once you have Python installed, you can install FastAPI using pip, which is the package installer for Python. Open your command prompt or terminal and enter the following command:

pip install fastapi

Step 3: Install Uvicorn

Uvicorn is a lightning-fast ASGI server implementation. You can install it using pip with the following command:

pip install uvicorn

Step 4: Start a FastAPI Project

Now that you have FastAPI and Uvicorn installed, you can start a new FastAPI project. Create a new Python file (e.g., app.py) and add the following code:


from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
return {"Hello": "World"}


Step 5: Run the FastAPI Server

To start the FastAPI server, run the following command in your command prompt or terminal:

uvicorn app:app --reload

Your FastAPI server should now be running, and you can access it by opening a web browser and navigating to http://localhost:8000/

Congratulations! You have successfully set up your development environment for FastAPI Python. You can now start building web APIs using FastAPI and Python.
