Python is a popular programming language that comes with a vast set of tools and features to help developers build robust applications. One of the most basic concepts in programming is numbers, and Python provides excellent support for numbers. In this blog, we will discuss the different types of numbers in Python and how to work with them using code snippets.
Python Numbers
Python provides three different types of numbers: integers, floating-point numbers, and complex numbers.
Integers: Integers are whole numbers that do not have a fractional component. For example, 1, 2, 3, 4, 5, and so on are integers. In Python, we can define an integer using the int() function. For example:
a = 10 b = int(20)
In this code snippet, we have defined two variables, a and b, and assigned them integer values using the int() function.
Floating-Point Numbers: Floating-point numbers are real numbers that have a fractional component. For example, 3.14, 2.5, 0.33, and so on are floating-point numbers. In Python, we can define a floating-point number using the float() function. For example:
a = 3.14 b = float(2.5)
In this code snippet, we have defined two variables, a and b, and assigned them floating-point values using the float() function.
Complex Numbers: Complex numbers are numbers that have both real and imaginary components. In Python, we can define a complex number using the complex() function. For example:
a = 2 + 3j b = complex(4, 5)
In this code snippet, we have defined two variables, a and b, and assigned them complex values using the complex() function.
Working with Numbers in Python
Once we have defined our numbers in Python, we can perform various operations on them, such as arithmetic operations, comparison operations, and logical operations.
Arithmetic Operations: Python supports all the standard arithmetic operations, such as addition, subtraction, multiplication, and division. For example:
a = 10 b = 5 # Addition c = a + b print(c) # Output: 15 # Subtraction c = a - b print(c) # Output: 5 # Multiplication c = a * b print(c) # Output: 50 # Division c = a / b print(c) # Output: 2.0
In this code snippet, we have defined two variables, a and b, and performed various arithmetic operations on them using the standard arithmetic operators.
Comparison Operations: Python supports various comparison operations to compare two numbers, such as greater than, less than, equal to, and so on. For example:
a = 10 b = 5 # Greater than c = a > b print(c) # Output: True # Less than c = a < b print(c) # Output: False # Equal to c = a == b print(c) # Output: False
In this code snippet, we have defined two variables, a and b, and performed various comparison operations on them using the standard comparison operators.
Logical Operations: Python supports various logical operations to combine two or more conditions, such as and, or, and not. For example:
a = 10 b = 5 c = 3 # and d = (a > b) and (b < c) print(d)
