One of the features of Python is its support for mathematical calculations, including infinity. Infinity is a concept that represents an unbounded value, a value that is greater than any finite number. In this tutorial, we’ll learn how to write infinity in Python.

## Steps:

### Step 1: Import the math module

To use infinity in Python, we first need to import the math module. The math module provides a range of mathematical functions that can be used in Python programs.

1 |
import math |

### Step 2: Use math.inf

Once we’ve imported the math module, we can use the math.inf attribute to represent infinity. Here’s an example code that assigns the infinity value to a variable:

1 |
x = math.inf |

### Step 3: Use negative infinity

In addition to positive infinity, Python also supports negative infinity. We can use the math.inf attribute with a negative sign to represent negative infinity. Here’s an example code that assigns negative infinity to a variable:

1 |
y = -math.inf |

## Conclusion:

In this tutorial, we learned how to write infinity in Python. By importing the math module and using the math.inf attribute, we can represent positive and negative infinity in our Python programs.

This feature can be useful in various applications where unbounded values need to be represented, such as in scientific research, data analysis, and more.
