How create a ramp with angle with python script

Question

I am learning how to use blender with python script. I want to draw a block with ramp. until here, I can generate a block but my problem is precisely on how do the ramp. if you can help me please.

I know the point from which I must start the ramp coordinates(0, 4, 5) and (0, -4, 5). the angle is 60°

Here is the script(this script allows to draw a cube. if you help me to do a ramp with coordinates and angle known please):

import bpy, bmesh
from math import *
from mathutils import Vector
import numpy as np
def create_mesh(polygon):
    coords = []
    pos = 0
    while pos < len(polygon) - 1 :
        i = polygon[pos]
    pos_suivant = pos + 1
    if pos_suivant &lt; len(polygon):
        j = polygon[pos_suivant]
        coords.append(i)
        coords.append(j)
        pos += 1
return coords




def draw(zTop, polygon):
    """this function receives 2 arguments :
    * zTop of type Integr: it's the maximum height
    * polygon of type list of tuple: it's coordinates of polygon 
    * this function allows to draw a cube
    """
    coords = create_mesh(polygon)
    bm = bmesh.new()
    for v in coords:
        bm.verts.new(v)
print(bm.verts)
#création de la base 
base = bm.faces.new(bm.verts)

#processus d'extrusion
hauteur = bmesh.ops.extrude_face_region(bm, geom=[base])

#ajout d'auteur d'extrusion
bmesh.ops.translate(bm, vec=Vector((0,0,zTop)), verts=[v for v in hauteur[&quot;geom&quot;] if isinstance(v,bmesh.types.BMVert)])
bm.normal_update()

me = bpy.data.meshes.new(&quot;Shape&quot;)
bm.to_mesh(me)
# ajouter à la scene
ob = bpy.data.objects.new(&quot;Shape&quot;,me)
bpy.context.collection.objects.link(ob)


coords = [(0,4, 0),(0,-4, 0), (4,-4, 0), (4,4, 0)]
draw(10, coords)

Add cube, resize, subdivide, move edge.

Image showing 3 test runs as in listed in code below

There are many ways to skin this cat, thought I would add a method to

Add a unit cube, scale to desired width x depth x height, and translate such that origin is as in question. (Could IMO use COG as origin and translate later)

The 4 vertical edges of cube are always the same index, will subdivide these, Insert new vertices into face using pyhton & bmesh Notice that the subdivide percent of each edge needs to be flipped depending on vert 0 of edge.

Finally the 11th original edge of cube is moved using Pythagoras (tangent)

import bpy

from mathutils import Matrix

context = bpy.context
def add_ramp(x, y, z, ramp, angle):
    bm = bmesh.new()
    bmesh.ops.create_cube(
            bm,
            size=1,
            matrix=(
                Matrix.Diagonal((x, y, z, 1)) @
                Matrix.Translation((.5, .5, .5))
                )
            )
    pc = ramp / z
    bm.edges.ensure_lookup_table()
    edge = bm.edges[11]
    edges = [bm.edges[i] for i in (1, 3, 6, 9)]
    bmesh.ops.subdivide_edges(
            bm,
            edges=edges,
            edge_percents={
                e : (pc if e.verts[1].co.z > e.verts[0].co.z else 1 - pc) 
                 for e in edges},
            use_grid_fill=True,
            cuts=1,
            )
    bmesh.ops.translate(
            bm,
            verts=edge.verts,
            vec=(0, (z - ramp) * tan(angle), 0),
            )
    me = bpy.data.meshes.new("Shape")
    bm.to_mesh(me)
    ob = bpy.data.objects.new("Shape",me)
    bpy.context.collection.objects.link(ob)
add_ramp(4, 8, 10, 5, radians(30))
add_ramp(4, 8, 10, 6, radians(45))
add_ramp(4, 8, 10, 5, radians(-30))
