If a coroutine awaits on a Future, the Task suspends the execution of the coroutine and waits for the completion of the Future. When the Future is done, the execution of the wrapped coroutine resumes.Python. pal_gen = infinite_palindromes() for i in pal_gen: digits = len(str(i)) pal_gen.send(10 ** (digits)) With this code, you create the generator object and iterate through it. The program only yields a value once a palindrome is found. It uses len () to determine the number of digits in that palindrome.Furthermore, some objects may implement dynamic attributes by overriding __getattr__, may be RPC proxy objects, or may be instances of C-extension classes. If your object is one these examples, they may not have a __dict__ or be able to provide a comprehensive list of attributes via __dir__ : many of these …1. When comparing instances of objects, the __cmp__ function is called. If the == operator is not working for you by default, you can always redefine the __cmp__ function for the object.
