+# Extract Text from PDF using Python Module
+
+## Modules Required
+- PyPDF2 - It is used in Python for PDF related operations
+
+## How it Works?
+* Import PyPDF2 Module to:-
+  * Read the pdf into the program to further manipulate it 
+  * Count the number of pages in the PDF
+  * Extract the text from a single PDF page
+* Initialize an empty string
+* A for loop parses through each page 
+  * The extractText() function is used to extract text from the parsed PDF page
+  * The extracted text is added to the emptry string initialized
+* After parsing is done, the string in which the extracted text is stored is written in a new file named **extracted_text.txt** using basic File Handling in Python
