API endpoint is the point of entry in a communication channel when two systems are interacting....

 Converting Pdf Text in to Audio Files: Libraries:- PyPDF , is a library in python that is used to read text from a pdf file. PyPDF2 · PyPI Pyttsx3 , is a text-to-speech convert library. pyttsx3 · PyPI Here we are using PyPDF library to read text from the pdf file and then we are converting the text into speech and save it as an audio file. Program: import pyttsx3 , PyPDF2 pdfrReader=PyPDF2.PdfFileReader( open ( 'File_1.pdf' , 'rb' )) audio=pyttsx3.init() for page_num in range (pdfrReader.numPages): text=pdfrReader.getPage(page_num).extractText() cleanText=text.strip().replace( ' \n ' , ' ' ) print (cleanText) audio.say(cleanText) audio.save_to_file(cleanText , 'File_1.mp3' ) audio.runAndWait() audio.stop() THANKS!!

- This is done by using a method called issubclass() provided by python. The method tells us if any class is a child of another class by returning true or false accordingly. - We can check if an object is an instance of a class by making use of isinstance() method: Example: class Parent (): pass class b (Parent): pass print ( issubclass (b , Parent)) #true print ( issubclass (Parent , b)) #False obj1=b() obj2=Parent() print ( "=======" ) print ( isinstance (obj2 , b)) #False print ( isinstance (obj2 , Parent)) #True THANKS!!
