Python beginners example: linear search

# Linear Search or Sequential Search Algorithm

def linear_search(array, to_find):
    pos = 0            # Starting position or index
    to_return = (False, 0)
    while (pos < len(array)):        # while index is less than length of array
        if (array[pos] == to_find):        # if array with index of var pos is equal to find
            to_return = (True, pos)            # no need to break loop cuz return appends func
            return to_return
        else: 
            pos = pos + 1        # if elem not found continue to next pos 
    return to_return

nums = [12, 34, 54, 88, 21]            
print(linear_search(nums, 88)            )
