Give me a code to maximum number made up of distinct digits whose sum is equal to N and the other steps required given the following:
Maximum number made up of distinct digits whose sum is equal to N | Function to find the largest positive number made up of distinct digits having the sum of its digits as N.
If given number is greater than 45 , print - 1.
Store the required number and the digit to be considered.
Loop until N > 0 and digit > 0.
If the current digit is at most N then , add it to number num.
Update the value of num.
Decrement N by digit.
Consider the next lower digit.
Add 0 at the end and return the number num.
Driver Code"
How can the above be solved in Python?

#Here is code to maximum number made up of distinct digits whose sum is equal to N and the other steps required.
 def largestNumber ( N ) :
	if ( N > 45 ) :
		return - 1
	num = 0
	digit = 9
	while ( N > 0 and digit > 0 ) :
		if ( digit <= N ) :
			num *= 10
			num += digit
			N -= digit
		digit -= 1
	return num * 10
N = 25
print ( largestNumber ( N ) )
