Blender 3D and python scripting - part 004.

In this tutorial, I will show you how to create a box from planes, see the screenshot:
You can see I used the math python package and I created rotation by radians and rotation object for three custom planes.
This is the source code:
import bpy

import math

def DegToRad(angle):
    """convert to radians"""
    return angle*(math.pi/180)


def RotOBJ(name, angles):
    """rotate obj to the specified angles"""
    rotation = [DegToRad(angle) for angle in angles]
    bpy.data.objects[name].rotation_euler = rotation
    
def create_plane_X(location, obj_name):

    obj = bpy.ops.mesh.primitive_plane_add(size=2, 
    calc_uvs=True, 
    enter_editmode=False, 
    align='CURSOR', 
    location=location, 
    rotation=(0, 0, 0), 
    scale=(0,0,0)
    )
    
    # rename the object
    bpy.context.object.name = obj_name
    # return the object reference
    return bpy.context.object

def create_plane_Y(location, obj_name):

    obj = bpy.ops.mesh.primitive_plane_add(size=2, 
    calc_uvs=True, 
    enter_editmode=False, 
    align='CURSOR', 
    location=location, 
    rotation=(0, 0, 0), 
    scale=(0,0,0)
    )
    
    # rename the object
    bpy.context.object.name = obj_name
    # return the object reference
    return bpy.context.object

def create_plane_Z(location, obj_name):

    obj = bpy.ops.mesh.primitive_plane_add(size=2, 
    calc_uvs=True, 
    enter_editmode=False, 
    align='CURSOR', 
    location=location, 
    rotation=(0, 0, 0), 
    scale=(0,0,0)
    )
    
    # rename the object
    bpy.context.object.name = obj_name
    # return the object reference
    return bpy.context.object

n = 1

planeX001 = create_plane_X((0,-1,0), "PlaneX-{:02d}".format(n))
RotOBJ(planeX001.name, [-90, 0, 0])
planeX002 = create_plane_X((0,1,0), "PlaneX-{:02d}".format(n))
RotOBJ(planeX002.name, [-90, -0, 0])

planeY001 = create_plane_Y((-1,0,0), "PlaneY-{:02d}".format(n))
RotOBJ(planeY001.name, [0, -90, 0])
planeY002 = create_plane_Y((1,0,0), "PlaneY-{:02d}".format(n))
RotOBJ(planeY002.name, [0, -90, 0])

planeZ001 = create_plane_Z((0,-0.25,1.66), "PlaneZ-{:02d}".format(n))
RotOBJ(planeZ001.name, [45, 0, 0])
