All You Need to Know about Linear Search in Python

PYTHON is one of the trending programming application now. Unlike C language it does not require many of the following commands and is made as much as user-friendly as possible. In this article, we will understand Linear Search in python in the following sequence:

Types of Searches

Basically, There are two types of searches.

• Linear Search
• Binary Search

In this blog, only linear search is discussed. Linear search Being one of the most popular and basic programs that the beginners learn. The below-given program executes the linear search. Linear search is searching a given number in an array of numbers that the user gives and printing the given position of the number out of all the inputs given.

What is a Linear Search?

A linear search, also known as a sequential search, is a method of finding an element within a list.

It checks each element of the list sequentially until a match is found or the whole list has been searched.

Code for Linear Search

lst = []

num = int(input("Enter size of list: t"))
for n in range(num):

    numbers = int(input("Enter the array of numbers: t"))
    lst.append(numbers)
x = int(input("nEnter number to search: t"))
found = False
for i in range(len(lst)):
    if lst[i] == x:
        found = True
        print("n%d found at position %d" % (x, i+1))
        break
if not found:
    print("n%d is not in list" % x)
input()

Function Explained

• Enter the size of the array.

• Press enter key after entering each input.

• Enter the array of numbers.

• Enter the number to be searched.

• The given position starting from numerical 1  will be displayed.

• If the number is not present in the list then the“number not found in the list” statement will be executed. 

• The result of the given program can be seen at the end of the program at the execution.
