The Python ternary operator returns a value based on whether a condition is True or False. It is similar to an if-else statement but is expressed in a single line. For understanding the ternary operator, we need to have an idea about conditional statements. Let's have a basic understanding of the if-else statement. We will have an if block followed by an else block here. The if block is executed when the given condition is True,  and the else block is executed if the given condition is False. The following is the basic syntax of the if-else statement - if condition: ... Read More

Multidimensional Dictionaries in python Multidimensional dictionaries are part of the dictionaries in Python, which are used to store data. Created by assigning a dictionary to a key within another dictionary, these structures are represented by curly braces {} and can accommodate any data type. Their mutable nature allows modifications after creation. They are composed of unique key-value pairs, separated by a colon (:). While keys are unique, values can be duplicated. Accessing values requires using keys, as dictionaries do not support indexing. To retrieve specific key values, use the key combined with indexing. Syntax The following is the syntax for ...

The XML is the markup language used to transfer the data. The XML syntax is the same as the HTML, whereas the tags are predefined in HTML and not in XML. This offers us to store the data between the opening and closing tags. In Python, dictionaries store data as key-value pairs. We can serialize a dictionary to XML format using two popular libraries: dict2xml (widely used) dicttoxml ... Read More

Double Quotes in PythonDouble quotes are used to represent a string or a character. The functionality of the single quotes and double quotes is the same. We can use any type of quote as per our requirement. The following is the syntax to create a string using double quotes in the Python programming language. str = “text” Example Let’s see an example to understand the functionality and usage of the double quotes in Python. Initially, we have created a string by passing the sentence in double quotes and assigned it to the variable str. Next we printed ... Read More

In python there are different types of data structures. Among them list, tuple, dictionary. All these three are used to store the data in the python programming language. What is a List? List is one of the data structures available in python which is used to store multiple values in a single data structure. We can create a list in Python using the square braces[ ]. It is mutable which means that we can modify a list once it is created. It takes multiple elements of different data types such as int, float, str etc which are separated by ... Read More

In Python, strings can be defined using single quotes ('), double quotes ("), or triple quotes (''' or """). For example, 'Hello' is a valid string. There are different types of quotes in Python. Each quotation is used in different scenarios as per the requirement. The following are the different types of quotations that we can use in the Python programming language. Single quotes Double quotes ... Read More

Tuple is one of the data structures of the Python programming language. It is used to store multiple values separated by commas in an ordered manner. It is immutable in the sense that once the tuple is created cannot perform any operations like deleting, appending, etc. The elements in the tuple can be int, float, string, or binary data types, and it allows duplicates of the elements. It uses indexing for accessing the elements. It allows a single element to be in a tuple. There are different ways to create the empty tuple. Let’s see each way in detail. ... Read More

The dictionary is the data structure available in python. Dictionaries are also known as associative memories or associative arrays. It is represented by curly braces {}. It stores the data in the form of key and value pairs. Data from a dictionary can be accessed by its key, unlike other data structures which use indexes. To retrieve the value associated with a particular key, one must use index values. As keys in dictionaries are unique, any immutable object such as tuples or strings can be used to identify them. However, values stored in dictionaries do not need to be ... Read More

In Python, list is one of the built-in data types. A Python list is a sequence of items separated by commas, enclosed in square brackets [ ]. The items in a Python list need not be of the same data type.  In this article, we will discuss different ways to create an empty list in Python. Using Square Brackets This is one of the simplest way to create an empty list to using square brackets[]. An empty list means the list has no elements at the time of creation, but we can add items to it later when needed. my_list=[] ... Read More

In Python, the ord() function converts a given character to the corresponding ASCII (American Standard Code for Information Interchange) integer. The ord() function raises a TypeError if you pass a string value as a parameter. Converting a single alphabet to its integer In the following example, we have converted a character 'A' into its Unicode using the ord() function - my_str='A' result=ord(my_str) print("Unicode of 'A'-", result) Following is an output of the above code - Unicode of 'A'- 65 Printing Integer values of all the alphabets We can use the ord() function to print all the Unicode characters ...
