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.

Python Do While Loops - GeeksforGeeks

In Python, there is no construct defined for do while loop. Python loops only include for loop and while loop but we can modify the while loop to work as do while as in any other languages such as C++ and Java.. In Python, we can simulate the behavior of a do-while loop using a while loop with a condition that is initially True and then break out of the loop when the desired condition is met.

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 List Slicing - GeeksforGeeks

Out-of-bound slicing. In Python, list slicing allows out-of-bound indexing without raising errors.If we specify indices beyond the list length then it will simply return the available items. Example: The slice a[7:15] starts at index 7 and attempts to reach index 15, but since the list ends at index 8, so it will return only the available elements (i.e. [8,9]).
