Can you provide a code to alternate Primes till N and the other steps required given the following:
Alternate Primes till N | Python 3 program to print all equal to n using Sieve of Eratosthenes.
Create a boolean array " prime [ 0 . . n ] " and initialize all entries it as true . A value in prime [ i ] will finally be false if i is Not a prime , else true ..
If prime [ p ] is not changed , then it is a prime.
Update all multiples of p.
Print all prime numbers.
for next prime to get printed.

#Here is code to alternate Primes till N and the other steps required.

	prime = [ None ] * ( n + 1 )
	for i in range ( len ( prime ) ) :
		prime [ i ] = True
	p = 2
	while p * p <= n :
		if ( prime [ p ] == True ) :
			for i in range ( p * 2 , n + 1 , p ) :
				prime [ i ] = False
		p += 1
	flag = True
	for p in range ( 2 , n + 1 ) :
		if ( prime [ p ] ) :

				print ( str ( p ) , end = " ▁ " )
				flag = False
			else :

	print ( " Following ▁ are ▁ the ▁ alternate " + " ▁ prime ▁ numbers ▁ smaller ▁ " + " than ▁ or ▁ equal ▁ to ▁ " + str ( n ) )
