In Python REST APIs, how do I manage dependencies?

Managing dependencies in Python REST APIs is crucial for ensuring your application runs smoothly. Proper management includes using tools like virtual environments, requirements files, and dependency managers.

# Example of managing dependencies in a Python REST API using pip and virtualenv

# Step 1: Create a virtual environment
python -m venv myenv

# Step 2: Activate the virtual environment
# On Windows
myenv\Scripts\activate
# On macOS/Linux
source myenv/bin/activate

# Step 3: Install required packages
pip install Flask

# Step 4: Create a requirements.txt file
pip freeze > requirements.txt

# Now you can share your requirements.txt with others to replicate the same environment
# To install the dependencies on another machine, use:
pip install -r requirements.txt
