Give me a code to sum of first N natural numbers with alternate signs and the other steps required given the following:
Sum of first N natural numbers with alternate signs | Function to find the sum of First N natural numbers with alternate signs.
Stores sum of alternate sign of First N natural numbers.
If is an even number.
Update alternateSum.
If i is an odd number.
Update alternateSum.
Driver Code"
How can the above be solved in Python?

#Here is code to sum of first N natural numbers with alternate signs and the other steps required.
 def alternatingSumOfFirst_N ( N ) :
	alternateSum = 0
	for i in range ( 1 , N + 1 ) :
		if ( i % 2 == 0 ) :
			alternateSum += - i
		else :
			alternateSum += i
	return alternateSum
if __name__ == " _ _ main _ _ " :
	N = 6
	print ( alternatingSumOfFirst_N ( N ) )
