Volume-calculation

• The volume function calculates the volume of various 3D shapes based on the provided shape type and corresponding metrics. It supports multiple geometric shapes and ensures input validation for accurate calculations.

Parameters

*args (float)

: A variable-length argument list representing the necessary metrics for the specified shape (e.g., radius, height, side length). The number of arguments required depends on the shape type.

type (str)

: A string that specifies the type of shape for which the volume is to be calculated. Supported types include:

'parallelepiped' 'cube' 'cylinder' 'sphere' 'cone' 'pyramid' 'tetrahedron' 'octahedron' 'icosahedron' Returns float: The calculated volume of the specified shape. Raises TypeError:

If any of the input metrics (*args) are not numbers (either int or float). If the type parameter is not a string. ValueError:

If the specified shape type is invalid (not one of the supported types). If the number of arguments does not match the expected count for the specified shape type. If any of the provided metrics are non-positive (less than or equal to zero).

Examples of usage

Calculate the volume of a cube with side length 3 volume_cube = volume(3, type='cube') # Returns: 27.0

Calculate the volume of a cylinder with radius 2 and height 5 volume_cylinder = volume(2, 5, type='cylinder') # Returns: 25.12

Visualization

In that module you can implement models of 2D figures in the graphical representation.

Example of usage

Draw a rectangle with A=4 and B=2

from functions_viz import *
from core import *

create_rectangle(4, 2, dimension="2d")

show()

As you saw here was used function show() in the end of the code. That is a powerfull instrument that gives us an opportunity to draw several figures in a one plot simultaneuosly.

Example of usage

Draw a rectangle with A=22 and B=12 Draw a circle with r=10

from functions_viz import *
from core import *

create_rectangle(4, 2, dimension="2d")
create_circle(10, dimension="2d")

show()

But you should be careful in usage because all figures are implemented in a queue-tendency. For example that code will cause some trouble because the circle is bigger than square and it gives no space for quadrate to be visible.

from functions_viz import *
from core import *

create_quadrate(2, dimension="2d")
create_circle(10, dimension="2d")

show()
