How to create AWS lambda function in python

Here are the steps to create an AWS Lambda function in Python:

1. Log in to your AWS account and navigate to the AWS Lambda console.
2. Click on the “Create Function” button.
3. Choose “Author from scratch” and enter a name for your function.
4. Select “Python” as the runtime and choose the version of Python you want to use.
5. Under “Permissions,” choose an existing or create a new execution role for your function. This role defines the permissions that your function will have to access other AWS services.
6. Click on “Create Function.”
7. You will now see the code editor for your function. You can write your Python code here.
8. In the “Function code” section, you can define the handler function for your Lambda function. The handler function is the entry point for your function and will be executed when your function is invoked. Here’s an example of a simple handler function in Python:

def lambda_handler(event, context):
    print("Hello, world!")

9. Once you’ve written your function code, click on the “Deploy” button to deploy your function to AWS Lambda.

That’s it! You’ve now created an AWS Lambda function in Python. You can now test your function by invoking it using the “Test” button in the AWS Lambda console.

How to Write Software Documentation With Python Sphinx

Sphinx is a popular tool used for generating documentation from source code. It can be used to generate documentation for Python projects, as well as other programming languages. Here are the steps to write software documentation with Python using Sphinx:

1. Install Sphinx: You can install Sphinx using pip by running the following command in your terminal:

pip install sphinx

2. Create a Sphinx project: Once you have installed Sphinx, you can create a new Sphinx project by running the following command in your terminal:

sphinx-quickstart

This will generate a new Sphinx project with some default settings. You can customize the settings as per your requirements.

1. Write documentation: Once you have set up your Sphinx project, you can start writing documentation for your Python project. You can write documentation in reStructuredText (reST) format, which is a markup language used by Sphinx. You can write documentation for your modules, classes, functions, and methods using the appropriate reST directives. Here’s an example:

.. module:: mymodule
   :synopsis: A brief description of what this module does.

.. function:: my_function(arg1, arg2)
   :param arg1: A description of arg1.
   :type arg1: The type of arg1.
   :param arg2: A description of arg2.
   :type arg2: The type of arg2.
   :return: A description of the return value.
   :rtype: The type of the return value.

   A description of what this function does.

4. Generate documentation: Once you have written your documentation, you can generate HTML documentation using the following command:

make html

This will generate HTML documentation in the _build/html directory.

5. View documentation: You can view your generated documentation by opening the index.html file in your web browser.

That’s it! You’ve now written software documentation with Python using Sphinx. You can customize your documentation further by using Sphinx extensions and themes.
