Introduction Python is a versatile programming language, provides several built-in methods for manipulating strings. Two commonly used methods are `casefold()` and `lower()`. While they may appear similar at first, there are some differences that make them unique and suited for specific use cases. Both methods help in case-insensitive string comparisons, it's crucial to highlight that their outcomes may vary depending on the local settings of our Python environment. Therefore, it is recommended to be aware of these settings and choose the method accordingly to ensure accurate results. Python – Casefold() and Lower() Casefold() The casefold() method is used to perform ... Read More

Introduction In the realm of programming, proficiency, and flexibility are key elements that engineers endeavor to realize. Python, a dialect known for its effortlessness and coherence, offers plenty of built-in capacities to help in accomplishing these objectives. One such work is itertools.zip_longest(), defined in Python's itertools module which plays a noteworthy part in dealing with iterables of unequal lengths. In this article, we dive into the internal workings of itertools.zip_longest(), investigating its preferences, utilize cases, challenges, and suggestions for different applications. Itertools.zip_longest() Explanation? The zip_longest() function combines multiple iterables together by "zipping" them into tuples. It does this by leveraging an ... Read More

NumPy is one of the popular libraries in python which is used to perform numerical calculations, scientific computations. It also allows us to work with large multi-dimensional arrays and matrices. There are many functions and modules in-built in the numpy library which are used to work with the different dimensional arrays. Converting a dictionary into a NumPy array We can convert a dictionary into a NumPy array by using the different modules and functions available in Numpy library. Let's see each way one by one. Using the numpy.array() function In NumPy, we have the function namely array(), which is used ... Read More

The Instance variables are generally used to represent the state or attributes of an object. Each instance of a class can have its own set of instance variables, which can store unique values. An instance variable is defined within the methods of a class and is accessible throughout the instance's lifespan. Accessing the instance variable in python The flexibility that comes with usage of instance variables allows each instance to maintain its own set of variables, enabling customized behaviour and data storage for different objects. Thus, accessing instance variables in python is a useful step.There are different ways to ... Read More

Sorting refers as the technique to arrange the elements in the defined order. There are different ways to sort the dictionary by keys in python. In this article we are going to learn those. Using sorted() function The sorted() function is used to sort the elements in the iterable data structures like tuple, dictionary, list etc. This function takes the iterable as the argument and returns the new sorted list containing the sorted elements as the output. Following is the syntax for using the sorted() function on dictionary. sorted(dictionary.keys()) Where, sorted is the function used to sort ... Read More

Pandas and Matplotlib are the libraries available in python to perform data analysis and visualization for the given input data. Following are some different plots that can be plotted using the pandas and matplotlib libraries.
