How to install turtle in python

To install turtle in python, nosotros have to run the below control in terminal:

          $ pip install turtle        

Python turtle methods

Some of the mostly used methods are:

• forward() – Information technology moves the turtle forward by the specified corporeality
• backward() – It moves the turtle backward by the specified amount
• right() – Information technology turns the turtle clockwise direction
• left() – It turns the turtle anticlockwise direction
• penup() – It stops cartoon of the turtle pen
• pendown() – Information technology starts drawing of the turtle pen
• color() – It changes the colour of the turtle pen

Python turtle speed

• The turtle.speed() method is used to change the speed of the turtle. Nosotros tin can laissez passer the value of the argument that it takes. It will render or gear up the speed of the turtle.
• The speed lies in the range of 0-ten.
• The speed values are in the following ways:
  • fastest – 0
  • fast – x
  • normal – half-dozen
  • slow – 3
  • slowest – 1
• The syntax used for the speed of turtle "turtle.speed(number)"

Example:

          import turtle  turtle.speed(i) turtle.forward(100) turtle.done()        

In this output, nosotros tin can see that the new window appears and the turtle speed is "1" which is the slowest and it is moving frontwards past 100 units.

Modify turtle size python

Here, nosotros will see how we can modify the turtle size in python

• To change the size of the turtle, we tin can increase or decrease the size of a turtle to brand it bigger or smaller. This will only change the turtle size without affecting the output of the pen every bit information technology draws on the screen.
• The syntax used for changing the size of a turtle is "turtle.shapesize(stretch_width, stretch_length, outline)".

Example:

          import turtle  tr = turtle.Turtle() tr.shapesize(x,5,1) turtle.washed()        

In this output, we tin can see that nosotros have used the "tr.shapesize(10,5,1)" for irresolute the size of the turtle and you can change size according to your preference. The new window will appear and y'all can see the turtle size is changed.

• Now, nosotros will label the graph filigree by defining a function and setting the position.

Case:

          import turtle  scr=turtle.Screen()  tr=turtle.Turtle() def draw_y(value):     tr.forrad(300)      tr.up()      tr.setpos(value,300)      tr.down()      tr.backward(300)      tr.upward()      tr.setpos(value+x,0)      tr.down()  def draw_x(value):      tr.frontwards(300)     tr.up()      tr.setpos(300,value)      tr.down()      tr.backward(300)      tr.upward()      tr.setpos(0,value+10)      tr.downwardly() def label():      tr.penup()      tr.setpos(155,155)      tr.pendown()      tr.write(0,font=("Verdana", 12, "bold"))      tr.penup()      tr.setpos(290,155)      tr.pendown()      tr.write("x",font=("Verdana", 12, "bold"))      tr.penup()      tr.setpos(155,290)      tr.pendown()      tr.write("y",font=("Verdana", 12, "bold"))  scr.setup(800,800)      tr.speed(10)  tr.left(ninety)    tr.colour('dark-green')  for i in range(thirty):      draw_y(10*(i+1)) tr.correct(xc)  tr.upwardly()  tr.setpos(0,0)  tr.down()   for i in range(30):      draw_x(10*(i+1))  tr.color('light-green')  tr.upward()  tr.setpos(0,150)  tr.down()  tr.forward(300)  tr.left(90)  tr.up()  tr.setpos(150,0)  tr.downwardly()  tr.forward(300) label()  tr.hideturtle() turtle.done()        

In this output, nosotros tin can run into a grid is fatigued on the new drawing board in Python.

Python turtle graphics not responding

In python turtle, we can face up the problem called "python turtle graphics not responding" and somewhen the program will end with no graphics output.

Example:

          import turtle tr = turtle.Turtle() tr.forward(150)        

By running the to a higher place code, we can see that the turtle window will non become opened. To solve this trouble refer to below example.

Case:

This problem occurs considering at the finish of the code nosotros have to say "turtle.done()" when you are done otherwise y'all will not become the turtle graphic screen.

          import turtle tr = turtle.Turtle() tr.forward(150) turtle.done()        

You can refer to the beneath screenshot, and now you lot will be able to come across the turtle graphics screen past using the above code.

Python turtle mainloop

The mainloop in python turtle make certain that the program continues to run. It is the final statement in the turtle graphics plan.

Instance:

          import turtle tr = turtle.Turtle() tr.backward(200) turtle.mainloop()        

In this output, we can see that the backward line is drawn for the interactive use of turtle graphics and the program continues to run.

How to activate check if push button is pressed on python turtle

• To activate the check in python, we have to employ the module called import turtle.
• Now, nosotros will define a office "def fun(x,y)".
• Hither, turtle.onclick(fun) is used to bind the function to a mouse click event on the turtle. When the user volition click on the turtle so it will perform the activity.

Example:

          import turtle  def fun(x,y):     turtle.right(ninety)      turtle.forwards(150)  turtle.speed(ii)  turtle.forward(150)  turtle.onclick(fun) turtle.done()        

In this output, we can meet that the line is drawn in a forward management, and when nosotros volition click on the turtle so it will move again, then on.
