To calculate the area of a triangle in Python, you can use the following formula:

				
					area = (s*(s-a)*(s-b)*(s-c)) ** 0.5

where a, b, and c are the lengths of the sides of the triangle, and s is the semiperimeter of the triangle, calculated as:

				
					s = (a + b + c) / 2

				
			
				
					# prompt the user to enter the lengths of the sides of the triangle
a = float(input("Enter the length of side a: "))
b = float(input("Enter the length of side b: "))
c = float(input("Enter the length of side c: "))

# calculate the semiperimeter of the triangle
s = (a + b + c) / 2

# calculate the area of the triangle using the formula
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5

# print the result
print("The area of the triangle is:", area)

To use this program, simply run it and enter the lengths of the sides of the triangle when prompted. The program will then calculate and print the area of the triangle.
