How to Print Negative Numbers in a List using Python

Submitted by razormist on Friday, June 21, 2024 - 23:30.

In this tutorial, we will program 'How to Print Negative Numbers in a List using Python.' We will learn how to display all the available negative numbers in a list. The objective is to automatically identify and extract all the possible negative numbers. I will provide a sample program to demonstrate the actual coding process in this tutorial.

This topic is very easy to understand. Just follow the instructions I provide, and you can do it yourself with ease. The program I will show you covers the basics of programming to display negative numbers in a list. I will do my best to provide you with a simple method for identifying and extracting negative numbers. So, let's start with the coding.

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.
  1. list1 = [-5, 8, -12, -35, -49, -56, 76, 93]
  2. num = 0
  3.  
  4. ret = False
  5.  
  6.  
  7. while True:
  8.         print("\n================== Print Negative Numbers in a List ==================\n\n")
  9.  
  10.         print("My numbers: ", list1)
  11.         print("\n")      
  12.         while(num < len(list1)):
  13.  
  14.  
  15.                 if list1[num] < 0:
  16.                         print(list1[num], end=" ")
  17.  
  18.        
  19.                 num += 1
  20.  
  21.         print("\n")
  22.         opt = input("\nDo you want to try again?(yes/no): ")
  23.  
  24.         if opt.lower() == 'yes':
  25.                 ret=False
  26.         elif opt.lower() == 'no':
  27.                 ret=True
  28.                 print("Exiting program....")
  29.  
  30.         else:
  31.                 print("Please enter yes/no:")
  32.                 break
  33.  
  34.         if ret == False:
  35.                 continue

This script prints the negative numbers in the list list1. It displays the list of numbers and then iterates through it, printing only the negative numbers. After completing this, it prompts the user to decide if they want to run the process again. If the user chooses to continue, the list is processed again; otherwise, the program exits.

Output:

There you have it we successfully created How to Print Negative Numbers in a List using 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!
