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.

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,

To quote a string in Python use single quotation marks inside of double quotation marks or vice versa. For instance: Output: Python Strings Python strings are sequences of characters and numbers. A string is wrapped around a set of single quotes or double quotes. There is no difference in which you use. Anything that goes

Python supports implicit line continuation. This means you can break long lines of code. For example, instead of this: You can write it like this: As a matter of fact, you should limit all lines of code to a maximum of 79 characters. Today, you are going to learn when and how to break long

To document functions in Python, use docstrings (triple quotation marks). For example: But why is this better than a regular comment with #? It is because you can then call the help() function on a method to see its documentation. For example, if you now call: You see this info about the function in the
