 Here is the code for the Sequential or linear search:
"""

target = 2
# Creates a variable poistion and assinging it a value of 2
lyst = [4, 3, 2, 1]
# create a variable called list and assiging it list

# Create a function call sequentailSearch that accepts two input parameters, target and lyst
def sequentialSearch(target, lyst):
    """Returns the positon of the target item if found or -1 otherwise"""
    position = 0
    #Creates a variable calle position and assigning it value of 0
    # Creatinge a while loop that checks if position which is 0 is less than
    # length of the list which is a true statment because lenght of the list is 4 and
    # position is 0
    while position < len(lyst):
        # Comparing the target is equal to lyst[position] the value at list of positon
        # return the position
        if target == lyst[position]:
            # return the positon
            return position
        position += 1
        # Increase the position by one
    return  -1
    # return -1 at th end
