can anybody explain

Question

class TriangleArea:
def __call__(self, a, b, c):
p = (a + b + c) / 2
result = (p * (p - a) * (p - b) * (p - c)) ** 0.5
return result
area = TriangleArea()
print(area(3, 4, 5))
can anybody explain how this returns 6.0 and what are these '*' means ..
I am stuck on magic methods and researching some materials myself to gain a grip of this..

Answer 1

Power of 0.5 is the same as square root Ala Pottra

Answer 2

* is multiply
/ is division (will output a float unless otherwise specified)
If you dont want the .0, try:
...
return round(result)
But i would leave it, less error.

Answer 3

p = 12/2 =6.0
result = (6.0 * 3.0 * 2.0 *1.0)**0.5 = 36.0**0.5 = sqrt(36.0) = 6.0
* is multiply and ** is power

Answer 4

Slick or floor division with //

Answer 5

where is the sqrt got executed

Answer 6

thankyou
