Python Interview Questions: Python Cache  Can you explain how you would use decorators in Python to add caching functionality to a specific function in a large application, and how you would handle cache invalidation? Yes, I can explain how to use decorators in Python to add caching functionality to a specific function in a large application and how to handle cache invalidation. First, I would create a decorator function called "cache" that takes in the function to be decorated as an argument. Inside the decorator function, I would define a dictionary to store the function's results, with the function's arguments as the keys and the results as the values. Next, I would create a nested function called "wrapper" which would check if the function's arguments existed in the dictionary. If they do, it will return the cached result. If they don't, it would call the original function, store the result in the dictionary, and then return the result. The decor

In Python, there are several built-in data types that you can use to store and manipulate data. In this tutorial, we will cover the following data types: Python Tutorial Chapter #2: Basic Data Types Integers: Integers are whole numbers that can be positive, negative, or zero. In Python, you can create an integer by assigning an integer value to a variable. For example: Floats: Floats are numbers with decimal points. In Python, you can create a float by assigning a float value to a variable. For example: Strings: Strings are sequences of characters. In Python, you can create a string by enclosing a sequence of characters in quotation marks. You can use single quotes or double quotes, but you must use the same type of quotes to start and end the string. For example: Lists: Lists are ordered collections of items. In Python, you can create a list by enclosing a comma-separated list of items in square brackets. Lists can contain items of any data type, and the items do not have to be of the

Exploring Data Visualization in Python The process of creating images or graphs to help us understand data is known as data visualization. It's similar to drawing a diagram of a math problem to help us understand it better. Python is a computer programming language that allows us to easily create these images. Python can read data from a spreadsheet or a text file and then generate various graphs or charts to display that data. As an example, suppose we have a list of grades for a class. Python can be used to generate a bar chart that shows how many students received each grade. The bar chart will show us which grades were the most common and which were the least common. Python offers a wide variety of libraries, or collections of code, that make it simple to build these visualizations. Matplotlib is a well-known library. It includes functions for creating line graphs, scatter plots, pie charts, and more. So, data visualization is the process of creating pictures or graphs to help
