Python | Linear search on list or tuples

  • Last Updated : 16 Jan, 2019

Let’s see a basic linear search operation on Python list and tuples.

A simple approach is to do linear search, i.e

  • Start from the leftmost element of list and one by one compare x with each element of the list.
  • If x matches with an element, return True.
  • If x doesn’t match with any of elements, return False.

Example #1: Linear Search on Lists




# Search function with parameter list name
# and the value to be searched
def search(list,n):
  
    for i in range(len(list)):
        if list[i] == n:
            return True
    return False
  
# list which contains both string and numbers.
list = [1, 2, 'sachin', 4,'Geeks', 6]
  
# Driver Code
n = 'Geeks'
  
if search(list, n):
    print("Found")
else:
    print("Not Found")
Output:



Found

Note that list are mutable but tuples are not.

Example #2: Linear Search in Tuple




# Search function with parameter list name
# and the value to be searched
def search(Tuple, n):
  
    for i in range(len(Tuple)):
        if Tuple[i] == n:
            return True
    return False
  
# list which contains both string and numbers.
Tuple= (1, 2, 'sachin', 4, 'Geeks', 6)
  
  
# Driver Code
n = 'Geeks'
  
if search(Tuple, n):
    print("Found")
else:
    print("Not Found")
Output:
Found
