Lets suppose one of the book have 3 unique id i want to search this id nd show all Related Information to that book ? How can i do tht

Answer 1

hi, sounds a little bit confusing to me. You mentioned that each book has a unique id number. And then you say ‘... one of the book have 3 unique id ...’ Can you explaine it again?
And the other information that is missing is the programming language you want to use.

Answer 2

hi, now it’s clear for me. I would suggest to store the data in a dict. This structure does always consists of a key: value pair. Key must be unique, value can contain data in our case a list with the detail data.

sample:

books = {
'1': ['Riverboat', 'Sam Gold', 22.50], ....}

Then you can search with the dict method .get for an id and print the detail data.

Answer 4

Don't use a list. If you need to search, given an unique key, dictionaries are the better data structures.

Lothar - clean code, but ... :D
A) If you use a list and your id is same as the index, use it to access the item directly! That results in O(1), so it's constant.
B) If that's not the case, use a dictionary so accessing is O(log n) with n the number of elements in your list

Otherwise your algorithm has O(n) and that's ... Not so good for large n.

Example:
log(1.000.000) = 6, compared to 1.000.000 ... is just a little better.
