This workshop covers the development of a Python application that reads client data from a CSV file, checks the current weather for each client's city using an API, and sends out promotional emails based on the weather condition (rain).
- Understand how to read data from CSV files in Python.
- Learn how to make API requests to gather weather data.
- Automate sending emails based on data-driven conditions.
- Purpose: To read from and write to CSV files in Python.
- Usage in Project: We use
csv.DictReader
to read client data from a CSV file and process it as a list of dictionaries.
- Purpose: To send HTTP requests in Python, essential for API interactions.
- Usage in Project: Used to make GET requests to the OpenWeatherMap API to fetch current weather data for each client's city.
- Purpose: SendGrid's Python library, used for sending emails through the SendGrid platform.
- Usage in Project: Utilized to programmatically send emails to clients. This includes composing the email and handling the sending process.
- Purpose: Provides a way of using operating system dependent functionality like reading or writing to the environment variables.
- Usage in Project: Used to access API keys stored in environment variables for security purposes.
- Purpose: To load environment variables from a
.env
file into the script, which is crucial for not hardcoding sensitive data like API keys. - Usage in Project: Implemented at the start of the script to load the OpenWeatherMap and SendGrid API keys.
- Introduction to the Project: Understanding the goal and the steps involved.
- Setting Up the Environment: Installing necessary packages and setting up API keys.
- Reading and Understanding CSV Data: Using the
csv
package to read client data. - API Interaction for Weather Data: Making GET requests to OpenWeatherMap API using the
requests
package. - Automating Email Dispatch: Composing and sending emails through SendGrid using the
sendgrid
package. - Bringing It All Together: Writing the main script to automate the entire process.
- Testing and Troubleshooting: Running the script and analyzing the results.
