How to find minimum distance between two numbers in a list with Python

Answer 1

import sys

def MinDistance(lst, number1, number2):
    min_distance = sys.maxsize
    size = len(lst)
    
    for i in range(size):
        for j in range(i + 1, size):
            if (lst[i] == number1 and lst[j] == number2 or 
                lst[i] == number2 and lst[j] == number1):
                min_distance = min(min_distance, abs(i - j));        
    
    return min_distance
 
 
lst = [2, 3, 7, 3, 3, 4, 8, 8, 8, 11, 9, 1, 3]

print(MinDistance(lst, 3, 8))
