**tutorial: using amazon textract to extract text from pdf files with python**

amazon textract is a service that automatically extracts text and data from scanned documents, pdfs, and images. in this tutorial, we will learn how to use amazon textract to extract text from pdf files using python.

**step 1: set up aws credentials**
before starting, you need to have an aws account and set up your aws credentials. you can create a new iam user with programmatic access and attach the `amazontextractfullaccess` policy to the user to grant necessary permissions.

**step 2: install boto3**
boto3 is the amazon web services (aws) sdk for python. you can use it to interact with aws services, including textract. install boto3 using pip if you haven't already:

**step 3: extract text from pdf with python**
now, let's write a python script that uses boto3 to interact with amazon textract and extract text from a pdf file.

in this script:
- we import the `boto3` library and create a textract client.
- we define a function `extract_text_from_pdf` that takes the file path of the pdf as input.
- we read the pdf file in binary mode and call the `analyze_document` method of the textract client to extract text from the pdf.
- we iterate through the response blocks to extract text lines and concatenate them into a single text string.
- finally, we call the function with the path to the pdf file and print the extracted text.

**note:** make sure to replace the `file_path` variable with the path to your own pdf file.

that's it! you have successfully extracted text from a pdf file using amazon textract and python. feel free to further process or analyze the extracted text as needed.
