Python Slicing – How to Slice an Array and What Does [::-1] Mean?

Here, we specify a start of index 2, no end, and a step of -1. Slicing here will start from index 2 which is 3. The negative steps mean the next value in the slice will be at an index smaller than the previous index by 1. This means 2 - 1 which is 1 so the value at this index, which is 2 will be added to the slice.

The Python Tutorial — Python 3.13.3 documentation

The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C).

Operators and Expressions in Python

That evaluates to 1, which is truthy. At that point, Python stops the evaluation because it already knows that the entire expression is truthy. Consequently, Python returns 1 as the value of the expression and never evaluates the remaining operands, f(2) and f(3). You can confirm from the output that the f(2) and f(3) calls don’t occur.

Python Lists - GeeksforGeeks

In Python, a list is a built-in dynamic sized array (automatically grows and shrinks). We can store all types of items (including another list) in a list. A list may contain mixed type of items, this is possible because a list mainly stores references at contiguous locations and actual items maybe stored at different locations.
