How to Print all Negative Numbers in a Range in Python
In this tutorial, we’ll learn how to program “How to Print All Negative Numbers in a Range in Python.” The objective is to safely print all the negative numbers in a range. This tutorial will guide you through the process step by step, ensuring that the result is correct and efficient. So, let’s get started!
This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will illustrate the proper way to print all the negative numbers. So, let’s dive into the coding process!
Getting Started:
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.- start, end = -15, 0
- while True:
- print("\n================= Print all Negative Numbers in a Range =================\n\n")
- n = list(map(lambda x: x if x < 0 else None, range(start, end + 1)))
- n = [num for num in n if num is not None]
- print(n)
- opt = input("\nDo you want to try again?(yes/no): ")
- if opt.lower() == 'yes':
- ret=False
- elif opt.lower() == 'no':
- ret=True
- print("Exiting program....")
- else:
- print("Please enter yes/no:")
- break
- if ret == False:
- continue
This program prints all negative numbers within a specified range using a lambda function combined with map() and list comprehension. It iterates through the range from -15 to 0, filters out only the negative numbers, and displays them as a list. The program repeats the process until the user decides to exit.
Output:
There you have it we successfully created How to Print all Negative Numbers in a Range in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
