Python | Linear search on list or tuples
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
