In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook....
21.Write a Python program to print all primes (Sieve_of_Eratosthenes) smaller than or equal to a specified number. In mathematics, the sieve of Eratosthenes, one of a number of prime number sieves, is a simple, ancient algorithm for finding all prime numbers up to any given limit. It do...

If condition evaluates to true, then not returns False and the if code block doesn’t execute.A common situation is one where you use a predicate or Boolean-valued function as a condition. Say you want to check if a given number is prime before doing any further processing. In that case...
