Accessing elements in a Python list is straightforward: you use the index of the element in square brackets. If you want to access the second item in a list, you would use index 1, as list indices start at 0.
fruits = ["apple", "banana", "cherry"]print(fruits[1]) # Outputs: bananaNegative Indexing
Python also supports negative indexing. If you want to access the last item in a list, you can use index -1.
print(fruits[-1]) # Outputs: cherrySlicing Lists
To access a range of items in a list, you can use slicing. Specify the start and end indices of the slice, separated by a colon, to return a new list containing the specified range.
print(fruits[0:2]) # Outputs: ['apple', 'banana']Note: The end index is not included in the slice.
Checking for Item Existence
To check if an item exists within a list, use the in keyword.
