Lists are one of the four most commonly used data structures provided by Python. A list is a data structure in Python that is mutable and has an ordered sequence of elements. In Python, a list is like a box in which you can keep many things like numbers, names, or your favorite fruits. Let us say you have a list like this: fruits = ["apple", "banana", "mango"] Here, each fruit has a position in the list. But in Python, we start counting from 0, not 1. So here is the indexing of apple, banana, and mango - ... Read More
The in operator in Python In Python, the in operator determines whether a given value is a constituent element of a sequence such as a string, array, list, or tuple. When used in a condition, the statement returns a Boolean result of True or False. The statement returns True if the specified value is found within the sequence. When it is not found, we get a False. In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. Square brackets ... Read More
In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. In this article, we will show you how the * operator works on a list in python. So we will show you different examples to understand how * works on a python list in the below section − Repetition Operator(*) A repetition operator is supported by sequence datatypes (both mutable and immutable). The repetition operator * creates several copies of that object and joins them together. When used with ... Read More
List is one of the most commonly used data structures provided by python. List is a data structure in Python that is mutable and has an ordered sequence of elements. In this article, we will discuss how to add objects to a list and the different ways to add objects, such as append(), insert(), and extend() methods, in Python. Using append() method In this method, we use append() to add objects to a list. The append() method adds a new element to the end of a list that already exists. Example 1 In this example, we used the append() method ... Read More
List is one of the most commonly used data structures provided by Python. List is a data structure in Python that is mutable and has an ordered sequence of elements. Here is a simple example of a list of integer values - lis= [1, 2, 3, 4, 5] print(lis) If you execute the above program, it produces the following output [1, 2, 3, 4, 5] In this article, we will look at different ways to find the maximum of the list in Python. For the above list the maximum or largest element of the list is 5. Using ... Read More
This article will discuss how to format date and time in Python. Python makes it easy to work with date and time with the help of the datetime module. You can format dates and times in different formats as per your needs. Datetime Module of Python The datetime module in Python offers methods for working with date and time values. To use this module, we must first import it using the following import keyword- import datetime Strftime() Function The strftime() function returns a formatted date and time. It accepts a format string that you can use to get the ... Read More
What is an Anonymous Inner Class In Java, an anonymous inner class is a class that doesn't have a name, we will directly define it at the time of instantiation. You can use it in cases where you need to override methods of a class (or interface) only once, without creating a separate named class. Syntax of Anonymous Inner Class When you are using a class to create an anonymous inner class in Java, use the following syntax: Class objectName = new Class() { // Override necessary methods }; When you are implementing an interface ...

The function strncpy() is used to copy the specified number of characters to the destination from the source. It is similar to the strcpy() function. In strncpy() function, we can specify the at most how many characters we want to copy from source to destination. In this article, we have a source string. Our task is to copy this string into a destination string using the strncpy() function and understand why it is insecure to use in C++. Syntax of strncpy() Function The syntax of the strncpy() function is as follows: char *strncpy(char *destination, char *source, size_t n); ... Read More
C++ Static Object A static object is declared with the static keyword. The static objects are initialized only once and stored in the static storage area. The static objects are only destroyed when the program terminates i.e. they live until program termination. In this article, we will understand static object, their types, and their examples. Syntax of Static Object The syntax for declaring a static object is as follows: Animal cat; //object declaration static Animal dog; //static object declaration Types of Static Objects The static objects can be of two types, which are mentioned below: ...

The static variables in C++ are defined using the static keyword. The static member variables in a class are shared by all the class objects as there is only one copy of them in memory, regardless of the number of objects of the class. All static data is initialized to zero when the first object is created, if no other initialization is present. In this article, we will understand the static member variables, their characteristics, and how static variables work in member functions with the help of example code. The characteristics of the static keyword are mentioned below: Characteristics ... Read More
