How to use list slicing In Python
This is a modified version of the first method, here instead of index for the value list, we pass the slicing range.
Syntax:
dictionary_name[key][start_index : end_index]
Example: using list slicing
Python3
# Creating dictionary which contains listscountry = { "India": ["Delhi", "Maharashtra", "Haryana", "Uttar Pradesh", "Himachal Pradesh"], "Japan": ["Hokkaido", "Chubu", "Tohoku", "Shikoku"], "United States": ["New York", "Texas", "Indiana", "New Jersey", "Hawaii", "Alaska"]}# extract the first 3 cities of Indiaprint(country["India"][:3])# extract last 2 cities from Japanprint(country["Japan"][-2:])# extract all cities except last 3 cities from indiaprint(country["India"][:-3])# extract 2nd to 5th city from usprint(country["United States"][1:5]) |
Output :
[‘Delhi’, ‘Maharashtra’, ‘Haryana’]
[‘Tohoku’, ‘Shikoku’]
[‘Delhi’, ‘Maharashtra’]
[‘Texas’, ‘Indiana’, ‘New Jersey’, ‘Hawaii’]
Python – Accessing Items in Lists Within Dictionary
Given a dictionary with values as a list, the task is to write a python program that can access list value items within this dictionary.
