Linear Search Python Code (Code Needs To Be Copied Into Python)
Townlist (Text Document Needed For Python File to Work)
Note: Make sure that townlist and the python file is in the same folder for the program to work. Remove/add comments where needed in order test out variants
Linear Search: (GCSE & A-Level)
The Linear Search starts at the beginning item in the list and checks each item one by one until it finds the intended search term.
- Start at the first item in the list.
- If this item is the search term, then the search is complete.
- If the item is not the search term, then move to the next item in the list.
- Repeat Step 2 until the search term is found or when there are no more items in the list.
Linear Search in Python:
|· Effective finding item in small data sets (Lists)||· Slowest type of search. Inefficient.|
|· Can be used on any list (sorted or unsorted)||· Number of operations/loops can vary depending on the size of the data set (list)|
|· Easy to program and easy to implement|
Big O Notation of Linear Search (A-Level):
|Best Case||Average Case:||Worst Case|
|· Constant||· Linear||· Linear|
|· O(1)||· O(n)||· O(n)|
