Python code to find the occurrences of digit d in the range

Comment

# Python3 program to count appearances
# of a digit 'd' in range from [0..n]
import math;
def getOccurrence(n, d):
     
    # Initialize result
    result = 0;
 
    # Count appearances in numbers
    # starting from d.
    itr = d;
    while(itr <= n):
         
        # When the last digit is equal to d
        if (itr % 10 == d):
            result += 1;
 
        # When the first digit is equal to d then
        if (itr != 0 and math.floor(itr / 10) == d):
             
            # increment result as well as number
            result += 1;
            itr += 1;
 
        # In case of reverse of number
        # such as 12 and 21
        elif (math.floor(itr / 10) == d - 1):
            itr = itr + (10 - d);
        else:
            itr = itr + 10;
 
    return result;
 
# Driver code
n = 11;
d = 1;
print(getOccurrence(n, d));
