Python Casting

Python is a flexible programming language that can handle a variety of data types. However, sometimes it is necessary to convert data from one type to another, and this process is called casting in Python. In this article, we will explore what casting is, how it works, and provide examples of how it can be used in Python programming. Specify a Variable Type Casting involves changing the data type of a value to a different type. Python provides several built-in functions to cast values to different data types. These functions include int(), float(), str(), and bool(), which can cast values to integers, floating-point numbers, strings, and booleans, respectively. Let's consider an example of casting in Python. Suppose we have a variable x that contains the value "5". This value is a string type, but we need to use it in a mathematical calculation, which requires it to be an integer type. In this case, we can use the int() function to cast the string value "5" to a...

Python Numbers

Python is a high level programming language that can work with different kinds of numbers such as whole numbers, numbers with decimal points, and complex numbers. This is all you need to understand about Python numbers. Integers: Integers are whole numbers with no decimal point. The int data type is utilized in Python to represent integers. These integers can take on positive, negative, or zero values. Example: ```python x = 5 y = -10 z = 0 ``` Floating-Point Numbers: Numbers that contain a decimal point are commonly known as floating-point numbers. Python uses the float data type to represent floating-point numbers. Floating-point numbers can have a value of zero, positive, or negative. Example: ```python x = 3.14 y = -2.0 z = 0.0 ``` Complex Numbers: A complex number comprises of a real component and an imaginary component. Within Python, these numbers are denoted by utilizing the complex data type. The real part is represented by the float or int data type, and the imaginary part is...

Python Strings

Python is a computer language that can be used for many things like creating websites, studying data, and building smart machines. Strings are an important way of storing and working with text in Python. This piece of writing will cover the basics of strings, including their definition, how they can be made, and a few typical actions you can do with them. What are Strings in Python? Python considers a string as a series of characters that signify text-based data. Such a string is composed of a group of characters that are enclosed either in single quotes ('') or double quotes (""). Strings can contain letters, numbers, symbols, and spaces, and can be of any length. For instance, "Hello, World!" is a valid string, as are 'Python is awesome!' and "12345". The choice of quotes is yours to make, as long as you're consistent. In Python, if a string begins with a single quote, it must be terminated with a single quote. Similarly, if a string ...

Python - Modify Strings

Python -  Modify Strings Python comes with some ready-to-use tools that make working with text easier. Upper Case Example If you apply the upper() method to a string in Python, it will convert all the letters in the string to uppercase and return the modified string: x =   "Hello, World!" print (x. upper() ) Lower Case Example If you apply the  lower()  method to a string in Python, it will convert all the letters in the string to uppercase and return the modified string: x =  "Hello, World!" print (x.lower()) Remove Whitespace The term "whitespace" refers to the space that appears before and/or after the text itself, and it is often desirable to eliminate this space. Example Using the ` strip()` method, you can eliminate any whitespace located at the start or end of a string : x =  " Hello, World! " print (x.strip())  # returns "Hello, World!" Replace String Example With the ` replace() ` method, you can substitute one string with an...
