turtle.shearfactor() function in Python (original) (raw)

Last Updated : 1 Aug, 2020

The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses Tkinter for the underlying graphics, it needs a version of Python installed with Tk support.

turtle.shearfactor()

This function is used to set or return the current shearfactor. It Shears the turtleshape according to the given shearfactor shear, which is the tangent of the shear angle.

Syntax : turtle.shearfactor(shear=None)

Parameter:

shear(optional): number, tangent of the shear angle.

Below is the implementation of the above method with some examples :

Example 1 :

Python3 `

importing package

import turtle

set turtle

turtle.speed(1) turtle.shape("turtle") turtle.up() turtle.goto(-150,0) turtle.down()

forward turtle by 100

turtle.forward(100)

set shear by +ive value

turtle.shearfactor(0.2)

forward turtle by 100

turtle.forward(100)

set shear by -ive value

turtle.shearfactor(-0.2)

forward turtle by 100

turtle.forward(100)

`

Output :

Example 2 :

Python3 `

importing package

import turtle

set turtle

turtle.speed(1) turtle.up() turtle.goto(-40,40) turtle.down()

set shear and apply to

all shapes

turtle.shearfactor(0.5)

get shape

sh=turtle.getshapes()

loop for pattern

for i in range(len(sh)): turtle.shape(sh[i]) turtle.forward(100+10i) turtle.right(90) turtle.forward(100+10i) turtle.right(90)

`

Output :
