Python Data Structure


Data Structure:

The data structure is a way to store and organize data in an efficient way. The data structure is a set of algorithms that we can use in any programming language to structure the data in the memory.

Data Structure in Python: 

Python provides a variety of useful built-in data structures, such as lists, sets, and dictionaries. For the most part, the use of these structures is straightforward.

  1. Tuple: Tuple is used to store multiple items in a single variable. It is a collection and unchangeable. Tuples are written within round brackets.  

Example: Tuple1 = ("apple", "banana")
         print(Tuple1)

  1.  List: A list is used to storing multiple items in a single variable. A list can also have another list of items. This called a nested list. We can use the index operator [ ] to access an item in a list.   Python provides multiple methods for lists.                                                                                           Example:  l1 = [ ]     # empty list                                                                                                                                  l1 = [2,3,'Hi',4.3]    # list with mixed data types.

Problem Statement:

You have an N-element tuple or a sequence that you would like to unpack into a collection of N variables.

To convert PDF files into an audio file, we use PyPDF2 and Pyttsx3 libraries. First, we use PyPDF2 for reading text from PDF and then use Pyttsx3 to convert extracted text into audio files. Let’s start with the PyPDF2 library. PyPDF2: PyPDF2 is a library in python that is used to read text from PDF. A Pure-Python library built as a PDF toolkit. It is capable of extracting document information, splitting documents page by page, merging documents page by page, etc. Pyttxs3: Pyttx3 is a text-to-speech library. It has many functions which will help the machine to communicate with us. It will help the machine to speak to us. How to install the above libraries? Pip install PyPDF2 Pip install pyttsx3 Example: import pyttsx3,PyPDF2 pdfObj = open('sample.pdf','rb') pdfreader = PyPDF2.PdfFileReader(pdfObj) speaker = pyttsx3.init() for page_num in range(pdfreader.numPages):          text = pdfreader.getPage(page_num).extractText()  ## extracting text from the PDF     clea
