In this tutorial, we will learn how to print an infinite series of numbers using the **Python** programming language. This could come in handy if you are developing a script that needs to generate a constantly updating sequence of numbers, such as prime numbers or Fibonacci numbers.

### Step 1: Import necessary Python modules

First, we will need to import the necessary Python modules to accomplish our goal. The **itertools** module will be used for creating iterators for generating an infinite sequence of numbers.

1 |
import itertools |

### Step 2: Define the infinite generator function

Next, we will define a generator function called **infinite_numbers**. This function will yield an infinite series of numbers, starting from 1.

1 2 3 4 5 |
def infinite_numbers(): num = 1 while True: yield num num += 1 |

### Step 3: Print the infinite numbers using itertools.islice()

Finally, we will use the **islice()** function from the **itertools** module to print a specified number of infinite numbers. This allows us to print a slice of the infinite sequence in a controlled manner.

1 2 3 4 5 |
numbers_to_print = 10 infinite_seq = itertools.islice(infinite_numbers(), numbers_to_print) for num in infinite_seq: print(num) |

This code will print the first 10 numbers of the infinite sequence.

1 2 3 4 5 6 7 8 9 10

You can set the **numbers_to_print** variable to any positive integer value to print a different number of infinite numbers.

## Full code

Here is the full code for printing an infinite series of numbers in Python:

1 2 3 4 5 6 7 8 9 10 11 12 13 |
import itertools def infinite_numbers(): num = 1 while True: yield num num += 1 numbers_to_print = 10 infinite_seq = itertools.islice(infinite_numbers(), numbers_to_print) for num in infinite_seq: print(num) |

## Conclusion

In this tutorial, we learned how to print an infinite series of numbers in Python. By using a simple generator function and the **itertools** module, you can easily create and control the output of an infinite sequence of numbers for various applications in your Python programs.
