IslandT: Find the smallest number within a list with python

In this example, we will create a python function which will take in a list of numbers and then return the smallest value. The solution to this problem is first to create a place holder for the first number within the list, then compares that number with other numbers within the same list in the loop. If the program found a number which is smaller than the one in the place holder, then the smaller number will be assigned to that place holder.

def find_smallest_int(arr):
    smallest = None
    for elem in arr:
        if(smallest == None or smallest > elem):
            smallest = elem
            
    return smallest
