Give me a code to maximum XOR value of a pair from a range and the other steps required given the following:
Maximum XOR value of a pair from a range | Method to get maximum xor value in range [ L , R ].
get xor of limits.
loop to get msb position of L ^ R.
construct result by adding 1 , msbPos times.
Driver code"
How can the above be solved in Python?

#Here is code to maximum XOR value of a pair from a range and the other steps required.
 def maxXORInRange ( L , R ) :
	LXR = L ^ R
	msbPos = 0
	while ( LXR ) :
		msbPos += 1
		LXR >>= 1
	maxXOR , two = 0 , 1
	while ( msbPos ) :
		maxXOR += two
		two <<= 1
		msbPos -= 1
	return maxXOR
L , R = 8 , 20
print ( maxXORInRange ( L , R ) )
