Type Conversion Between Data Types in Python

Image
In Python, you can convert one data type to another through a process known as type conversion or type casting. This allows you to change the representation of data from one form to another based on your program's requirements. In this article, we will explore the various methods available for type conversion in Python. Implicit Type Conversion Python automatically performs implicit type conversion when it encounters expressions or operations involving different data types. For example, if you try to add an integer and a floating-point number, Python will convert the integer to a float and perform the addition. This is known as implicit type conversion or coercion. Here's an example: Python code x = 5 y = 3.14 result = x + y # Implicit type conversion of x to float In the example above, the integer value of x is implicitly converted to a float to perform the addition operation with y. Explicit Type Conversion Python also provides built-in functions to e...

Text Data Type (str) in Python

Image
In Python, the text data type is represented by the str class. Strings are used to store and manipulate textual data. They can contain a sequence of characters, including letters, numbers, symbols, and whitespace. In this article, we will explore the basics of working with text data in Python. Creating a String To create a string in Python, you can enclose the text within single quotes ('') or double quotes (""). For example: python code message = 'Hello, world!' name = "Alice" Both single quotes and double quotes can be used interchangeably to define a string. This flexibility allows you to include quotes within a string by using the opposite type of quote. For example: python code quote = "He said, 'Python is awesome!'" Accessing Characters in a String You can access individual characters in a string using indexing. Python uses zero-based indexing, which means the first character has an index of 0, the second ch...

Numeric Data Types in Python: int, float, complex

Image
Python is a versatile programming language that provides several numeric data types to work with. These data types include integers, floating-point numbers, and complex numbers. In this article, we will explore these numeric data types and their usage in Python. Integers (int): Integers are whole numbers without any decimal points. They can be positive, negative, or zero. In Python, you can declare an integer variable by assigning a numeric value without decimal points. For example: python code x = 5 y = -10 Here, x and y are variables of the integer data type. Floating-Point Numbers (float): Floating-point numbers, commonly known as floats, represent decimal numbers. They can have both whole and fractional parts. In Python, you can declare a float variable by assigning a value with decimal points. For example: python code pi = 3.14159 temperature = 98.6 Here, pi and temperature are variables of the float data type. Complex Numbers (complex): Complex numbers...
