Write me a code to minimize cost required to complete all processes and the other steps required given the following:
Minimize cost required to complete all processes | Function to find minimum cost required to complete all the process.
Sort the array on descending order of Y.
Stores length of array.
Stores minimum cost required to complete all the process.
Stores minimum cost to initiate any process.
Traverse the array.
If minCostInit is less than the cost to initiate the process.
Update minCost.
Update minCostInit.
Update minCostInit.
Return minCost.
Driver Code.
Function Call"
How can the above be solved in Python?

#Here is code to minimize cost required to complete all processes and the other steps required.
 def minimumCostReqToCompthePrcess ( arr ) :
	arr . sort ( key = lambda x : x [ 0 ] - x [ 1 ] )
	n = len ( arr )
	minCost = 0
	minCostInit = 0
	for i in range ( n ) :
		if arr [ i ] [ 1 ] > minCostInit :
			minCost += ( arr [ i ] [ 1 ] - minCostInit )
			minCostInit = arr [ i ] [ 1 ]
		minCostInit -= arr [ i ] [ 0 ]
	return minCost
if __name__ == " _ _ main _ _ " :
	arr = [ [ 1 , 2 ] , [ 2 , 4 ] , [ 4 , 8 ] ]
	print ( minimumCostReqToCompthePrcess ( arr ) )
