Creating different conic sections and curves
Project description
Creating Conic Sections and Mathematical Curves using Python Turtle
We have created a Python package 'turtle_conics'.Using this package, we can draw different curves like Ellipse ,Parabola, Hyperbola in Python Turtle in any orientation as you like. We can also draw many beautiful Mathematical Curves using Python Turtle.
Feel free to contribute with a pull request if you want to add any Curve, also check out the Source code for the Package in my Github Repository
FEATURES
Simple function to create any of the above mentioned curves by importing functions from all_curves module specifying the arguments. Can be used inside Looping structures to create different patterns.

*NOTE: While Importing the Package, the name of the package is 'turtle_conics' and not 'turtleconics'.
 For importing all functions inside the package:
import turtle
from turtle_conics.all_curves import *
#Now make a function call for any of the curves
turtle.done()

Package Description
The 'turtle_conics' package consists of module 'all_curves' with 8 functions to draw Ellipse, Parabola, Hyperbola, Cardioid, Heart curve,Butterfly curve, Leminiscate, Hypocycloid and Epitrochoid.
Latest Curves
Epitrochoid These are set of curves formed when a point attached to Outer Circle(with radius 'b') rolls around the outside of another fixed Circle(with radius 'a').
We can draw different types of Epitrochoids:  We can draw different types of limacon(i.e when a=b)  We can draw different types of Hypocycloids(i.e when b=ht)
def epitrochoid(a, b, ht, no_of_loops=None, h=None, k=None)
 a:It is the radius of the Inner circle.
 b: It is the radius of Outer circle which is rolling outside the Inner circle to generate these set of curves.
 ht: It is the distance of the pt(whose locus is this curve) from centre of Outer Circle.
 no_of_loops(Optional): This parameter is for the no of loops. NOTE: This parameter is useful when the ratio 'a/b' is a fraction and we can adjust the no of loops accordingly.
 h,k:(Optional) For drawing an epitrochoid with centre of Inner circle at (h,k).By default both are zero.Using this parameter we can draw these curves at any position in the Turtle Window. NOTE: When the ratio of radius of Outer Circle to radius of Inner Circle (i.e a/b) is fractional, then the curve may or may not be closed entirely hence we can adjust the value for no of loops.
Hypocycloid
These are a set of curves formed when a Circle rolls inside another fixed Circle.
We can draw different types of Hypocycloids:  Curves having integer value of 'n'(Curves like Astroid,Deltoid etc)  Curves having Fractional/Rational value of 'n' Here 'n' is ratio of radii of Outer circle with Inner circle(a/b).
def hypocycloid(a, b, no_of_loops=None, h=None, k=None)
 a:It is the radius of the Outer circle.
 b: It is the radius of Inner circle which is rolling inside the Outer circle to generate these set of curves.
 no_of_loops(Optional): This parameter is for the no of loops required to complete any curve.NOTE: If while using this function, any curve is incomplete then by adjusting the value to this parameter we can complete that curve.
 h,k:(Optional) For drawing any hypocycloid with centre of Outer circle at (h,k).By default both are zero.Using this parameter we can draw these curves at any position in the Turtle Window. NOTE: In this Function we have defined the no of loops required for drawing curves with value of 'a/b' as fractional only upto the ratio '1/10'(i.e 1/2, 1/3,1/4 and so on upto 1/10).Hence if we provide different radii resulting in ratios that were not defined in this function, then the no of loops is set to a default value of '100'.Hence we can adjust the no of loops accordingly to complete any curve..
LEMINISCATE
We can draw 2 types of leminiscate:  Along X axis(Horizontally)  Along Y axis(Vertically)
def leminiscate(a, orientation, angle=None, angle_unit=None, h=None, k=None)
 a:It defines the size of the leminiscate.

 a:It defines the Horizontal size of the butterfly.
 b:It defines the Vertical size of the butterfly.
 n:(Optional) It is the Number of Turns to draw a Butterfly. By Default it is set to 602 turns.
