In Python, the finally statement is helpful with error handling to ensure code executes. For example, here the something_else() call does not run because it is not in an finally block: But by placing it inside a finally block, it gets executed no matter what: This is a comprehensive guide to the finally statement in […]

The Python reduce() function works such that it: Applies a function to the first and the second element of an iterable. Stores the result. Applies the function to the third element and the result. Continues this process until no values left. In other words, the reduce() reduces an iterable into a single cumulative value. For

To find the largest number in a list in Python: Here is how it looks in code: Output: This is the naive implementation of finding the largest number. But there are also some useful built-in mechanisms you can use. In this guide, you learn different ways to find the maximum value in a list in

To find the average of a list in Python: Sum up the elements of a list. Divide the sum by the length of the list. For instance, let’s calculate an average of a list of numbers: Output: This is a comprehensive guide to calculating the average of a list in Python. In this guide, you

To find a word in a file using Python: For example, let’s check where (if any) the word “test” is in a file called “example.txt”. In my case, the word is found in the second line. So the output is: (The enumerate(file, start=1) matches each line with an index. Line 1 has an index of

An abstract method is a method that has a declaration but no implementation. A Python class with at least one abstract method is called an abstract class. To create an abstract class in Python, use the abc module. For example, here is an abstract class Pet: The idea of an abstract class is that when

The maximum recursion depth in Python is 1000. You can verify this by calling sys.getrecursionlimit() function: You can change the limit by calling sys.setrecursionlimit() method. For example: Consider this a dangerous action! If possible, instead of tweaking the recursion limit, try to implement your algorithm iteratively to avoid deep recursion. Python Maximum Recursion Depth Exceded

To start your journey as a Python developer, you need to install Python into your system. To do this, open up python.org/downloads From there, download the most recent version by clicking on the yellow button Next, head over to your downloads folder and click the downloaded Python package to start the installation. If you are

To ask for user input in Python, use the built-in input() function. For example: Output example: In addition to asking for simple string input like this, you also want to learn how to: Ask for multiple inputs in one go. Ask for input again until valid input is given. To learn more about these, keep

You can use Python single quotes and double quotes to create strings. There is no difference between the two. It does not matter which approach you use. Regardless of which one you use, please be consistent with it in the codebase. Do not write one string with double quotes and the other with singles. Also,
