Python, looping exercises

From turtle import *fillcolor ("Red") Begin_fill () for I in range (5): Up    ()    Goto (0,-20*i) down    ()    Circle ( 20*i) End_fill ()

First, Concentric circle

Second, the sun flower

From turtle import *color (' Red ', ' yellow ') the Begin_fill () while True:    forward (+) right (in)    if ABS (POS ( )) <1:        Breakend_fill () Done ()

Third, flag

From turtle Import *setup (640,440,0,0) color ("yellow") bgcolor ("Red") FillColor ("Yellow")  def llf_goto (x, y):    Up ()    goto (x, y) down    ()     def Llf_draw (r):    Begin_fill () for    I in range (5):                 forward (R)        Right (144)    End_fill () Llf_goto ( -286,132) Llf_draw ( -132,180) Llf_goto ( -88,132) Llf_draw Draw (Llf_goto) ( -88,72) Llf_draw (+) Llf_goto ( -132,22) Llf_draw (50)

Four, draw diamond Flower

Import Turtledef draw_1 (LLF): Llf.forward (+) llf.right (GB) Llf.forward (+    )    Llf.right (135) def Draw_2 ():    window=turtle. Screen ()    Window.bgcolor ("Blue")    llf=turtle. Turtle ()    llf.shape ("Turtle")    Llf.color ("orange")    llf.speed ("fastest") for    I in range (1,37):        draw_1 (LLF)        draw_1 (LLF) llf.left (llf.right llf.forward) 155 (    ' Green ')    Llf.forward (145)    Window.exitonclick () draw_2 ()
