In this article, we will see the differences between two common ways of adding elements to lists in Python: the append method and the "+" operator. The append() method is used to add elements to the list by utilizing a mutator() method. The '+' operator is used to create a new list with the capacity for one more element. Behaviour of "+" with Python Lists Python accesses each element of the first list by using the '+' operator. When the '+' symbol is used, a new list with the capacity for one more element is produced. The old ... Read More
Sequence Data Types are used to store data in containers in the Python programming language. The different types of containers used to store the data are List, Tuple, and String. Lists are mutable and can hold data of any type, whereas Strings are immutable and can only store data of the str type. Tuples are immutable data types that can store any sort of value. So let's discuss these data types one by one in the coming section - List The sequential data-type class includes the list data type. The list is the only mutable data type in the sequential ...

No, we can not place any code after throw statement, it leads to compile time error. The compiler will show this error as unreachable statement. In Java, the throw statement immediately terminates the current flow of execution, therefore, the code immediate to a throw statement will not be executed. The control is then transferred to the next catch block or the caller method. The throw Keyword in Java The throw keyword is used to throw an exception manually. Whenever it is required to stop the execution of the functionality based on the user-defined logical error condition, we will use this ... Read More
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 ...
