Before going to the program first let us understand what is a Linear Search?

Linear search:

          Linear search is the simplest search algorithm. It is also called a sequential search.

Linear search is a method for finding a particular value in a list that checks each element in sequence until the desired element is found or the list is exhausted.

For Linear search, the list need not be ordered.

Program code for Linear Search in Python:

# Python Program for Linear Search
# Initialize an empty list and the flag variable
array = []
element_found = False

size = int(input("Enter the size of an array: "))

# Read the elements from the user
for i in range(size):
    elements = int(input("Enter the Element: "))
    array.append(elements)

# Read the element to be searched from the user 
element = int(input("Enter the element to be searched: "))

for i in range(size):
    if element == array[i]:
        position = i
        element_found = True
        break

if element_found:
    print("The element is in the list and its position is: ", position + 1)
else:
    print("The element is not found")

Output:
