Write a program to Calculate the Area of a Triangle in Python

Python 3 Code:

Output:

The code you provided is a simple Python program that calculates the area of a triangle given the lengths of its three sides.

The program starts by using the `input()` function to prompt the user to enter the three sides of the triangle, `a`, `b`, and `c`. The user’s input is stored as a string, so it needs to be converted to a float using the `float()` function.

Next, the program calculates the semi-perimeter of the triangle by dividing the sum of the three sides by 2 and assigns the result to the variable `s`.

Then, the program uses the Heron’s formula which is a method for finding the area of a triangle when you know the lengths of all three sides. The formula is: area = (s*(s-a)(s-b)(s-c)) ** 0.5

Finally, the `print()` function is used to output the area of the triangle to the console. The `%` operator is used to format the output and insert the value of `area` into the string that is passed to the `print()` function. The `%0.2f` within the string is a format specifier, it tells Python to format the number as a floating-point number with 2 decimal places.

The output will depend on the input provided by the user, for example, if the user inputs 3, 4 and 5 as sides, the output will be “The area of the triangle is 6.00”
