Submitted by razormist on Wednesday, March 20, 2024 - 22:56.

In this tutorial, we will program 'How to Calculate the Area of a Triangle in Python'. We will gain a better understanding of how to calculate the area of a triangle. The main goal here is to use a formula that will provide accurate results. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for calculating the area of a triangle. I will do my best to provide you with the easiest method of creating this program, called 'Calculate the area of a triangel'. 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 calculate the area of a triangle. To do this, simply copy and paste these blocks of code into the IDLE text editor.

while True:
   ret=False
 
   print("\n\n================= Calculate the Area of a Triangle =================\n\n")
 
 
   a = int(input("Enter the A value: "))
   b = int(input("Enter the B value: "))
   c = int(input("Enter the C value: "))
 
 
   s = (a + b + c) / 2
 
 
   area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
   print('The area of the triangle is %0.2f' %area)
 
   user_input=input("\n\nTry Again? (Yes/No): ")
   if user_input.lower()=='no':
      print("Exit program.")
      break
 
   elif user_input.lower()=='yes':
      ret=True
 
   else:
      print("Wrong input.")
      ret=True
 
 
   if ret:
      continue

In the provided code, we simply enclosed the code with a while loop to allow for continuous execution of the program. To calculate the area of a triangle, we used a formula that will provide the correct result.
