Python refers to the high-level programming language that has various tools and built-in functions to analyze text data. This problem statement is a common task that uses some built-in functions- filter(), isdigit(), isalpha(), findall(), split(), and, append() to find the both alphabet and numbers using Python. Let’s see how to take the input of the program to get the result: Input my_text = "WELCOME TO CLUB100" Output CLUB100 Syntax The following syntax is used in the examples- filter() The filter() method is applied when it filter the items based on specific conditions. In simple terms, it allows ... Read More
The tuple list defines the two different datatypes of Python that represent the static and dynamic characteristics respectively. In a dictionary, we can create keys using tuples whereas lists cannot be used as keys. In Python, we have some built-in functions like next(), items(), index(), lambda, and, min() will be used to Find the first element by the second in the tuple list. This type of circumstance occurs when the second element holds the important information as a key for identifying the desired tuple. Let’s take an example of this: The given tuple list, my_tup = [("India", 35), ("Indonesia", 12), ... Read More
The dictionary is one of the most popular among four datatypes known for unordered collection of key-value pairs. The Python matrix will be used to represent the list of lists whereas an inner list represents the row-value of a matrix. A coordinate dictionary is defined as tuples to set the rows and columns by giving coordinates value. In Python, we have some built-in functions such as len(), range(), zip(), etc. that can be used to solve Convert Matrix to Coordinate dictionary. Syntax The following syntax is used in the examples- len() The len() is a built-in method in Python ... Read More
Promises, in JavaScript, can be used to simplify asynchronous programming, making it easier to handle asynchronous operations like I/O operations or communicate with an external system or machine. Promises are objects that represent the eventual completion or failure of an asynchronous operation and its resulting value. They provide an easy way to deal with asynchronous code, allowing us to write cleaner and more readable code. Here we will discover what are promises in javascript and how to use them to incorporate asynchronous programming behaviour into our control flow, in this tutorial. A promise has 3 states − Pending − ... Read More
The indices are the position of the elements present in the list whereas K defines the specific value to target the smallest element from the list. Sometimes, we are working in the field of web development and database these tasks generally occur to solve this problem statement. In Python, we have built-in functions like sorted(), range(), len(), etc. that will be used to find the indices for k Smallest elements. Syntax The following syntax is used in the examples- sorted() The sorted() is an in-built function in Python that helps to return the new sorted list while ... Read More
The position of the smallest value within a list is indicated by the index of the minimum element. Each list element has a distinct index that increases by one with each additional element after the first, starting at zero for the first element. By determining the index of the minimum element, we can locate the exact position of the smallest value within the list. In Python, we have some built-in functions like min(), index(), argmin(), lambda(), and, enumerate() to find the index of the minimum element in the list. Syntax The following syntax is used in the examples- min() ... Read More
Lists are a powerful data structure in Python that can hold many values of various types. We may come across nested lists where the items themselves are lists. In such circumstances, flattening the list and retrieving individual elements from the hierarchical structure may be essential. In Python, we have some built-in functions- chain(), extend(), and append() that can be used to solve the Flatten List to individual elements. Let’s take an example of this: Input # Flatten List my_list = [[11, 21, 31], [20, 30, 40], [4, 5, 6], [1, 2, 3]] Output # individual element in the list ... Read More
In this article, we will learn how to use named arguments in javascript, and how we can use it to significantly enhance code readability and maintainability. Javascript allows us to use named arguments, which eliminate the need for the order of parameters to matter during function execution. We may then access the arguments by name inside the function definitions. Let’s look at some of the examples and methods to understand the concept better − Example 1 - Passing Objects as Arguments We can pass an object as an argument to the function to achieve named−argument functionality. This uses the ... Read More
The dictionary is one of the famous datatypes of Python that consist of keys with value pairs. The strings list is the set of elements that are represented either in a single or double quotation. In Python, we have some built-in functions such as keys(), set(), intersection, and append() will be used to find the dictionary keys present in strings List. Let’s take an example of this. There are two available sets:- The given dictionary, {'T': 1, 'M': 2, 'E': 3, 'C': 4} The given list, [T, A, B, P, E, L] Therefore, the final result becomes [T, E]. ... Read More
The tuple is a popular datatype of Python that represents the collection of objects or elements separated by commas. The frequency of data type defines the total number of counts of a specific variable type. Python has four primitive variable types: integer, float, boolean, and string. In Python, we have some built-in functions such as type(), isinstance(), filter(), lambda, len(), and list() will be used to Find the frequency of a given Datatype in a Python tuple. Syntax The following syntax is used in the examples- type() The type() is an in-built function in Python that returns the type ... Read More
