How to create an empty tuple in Python?
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 MoreWhat are Getters/Setters methods for Python Class?
Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of wrapping data and the methods that work on data within one unit. This restricts accessing variables and methods directly and can prevent the accidental modification of data. To prevent accidental change, an object’s variable can only be changed by the object’s method. Those types of variables are known as private variables. In Python, getters and setters are methods used to access and modify private attributes of a class. These methods are ...
Read MoreHow do we use double quotation in Python?
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 MoreHow to find out if a Python object is a string?
The class is a blueprint, which is used as the reference to create the object. This contains attributes and methods in a logical entity.Let’s understand the usage of the class in an object-oriented programming language through a real-time scenario. Consider a library. In a library, we will have different numbers of books. Now we want to track every book from the library. For a book, we will have different attributes like book name, ...
Read MoreHow to declare a multi dimensional dictionary in Python?
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 ...
Read MoreHow to serialize Python dictionary to XML?
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 MoreWhat is operation of <> in Python?
Understanding the Operator in Python The is one of the operators available in Python. The present version that we are using is Python 3. The previous version was Python 2. Some of the operators in Python 2 don't support in Python 3. is used in Python 2, which is not supported in Python. The operator != is used in Python 3. The functionality of the or != is to represent not equal to. The output of these operators is in the format of Boolean values True or False. Syntax The following is the syntax for using ...
Read MoreWrite a python program to count total bits in a number?
Python Program to Count Total Bits in a Number To calculate the total bits in a number, convert it to binary using the bin() function. A bit represents data as 0 or 1, and 8 bits make a Byte. Bits are essential for data transmission, storage, and arithmetic operations, and bitwise operations are also possible. The output of bin() starts with 0b, followed by the binary digits. To find the total bit count, remove the leading 0b after conversion. Syntax Following is the Syntax for the bin() function. Where, number is the number to be converted into binary format variable_name ...
Read MoreHow do I look inside a Python object?
Python object is belongs to the object oriented programming language. We previously have idea and knowledge regarding the python object. provides several built-in functions that help you inspect various aspects of objects. Some of these methods, including help(), type(), dir(), id(), hasattr(), getattr(), and callable(). Using the help() function If we want to inspect the python object we have a built function of python named help(). That provides documentation about an object, including its methods and attributes. Example In the following code, we imported the power function from the math module. Next we applied the inbuilt function help() on power ...
Read MoreHow we can compress large Python files?
We have to work with large size files in Python. If we use the large files, they occupy more space, and it isn't easy to handle the large files too. In such cases, we have a module in Python to work with the large files. The module we can use to handle large files is zipfile. By using this module, we can compress a large file into smaller files in Python. The following is the process that we have to follow for compressing the large files. ...
