Python Turtle Assymetrical Branch

Ok, it's my last fractal this month, :D

`import turtleimport numpy#buat pola di sini#kura-kura menghadap ke atasturtle.shape("turtle")turtle.speed(10)turtle.left(90)lv  = 11l   = 100dl  = 3./4.sl  = 17sr  = 39bl  = 1./2.br  =1./4.turtle.penup()turtle.backward(l)turtle.pendown()turtle.forward(l)def maju(l,level):    level   += 1    turtle.backward(l*bl)    l       = l*dl    turtle.left(sl)    turtle.forward(l)    if level<=lv:        maju(l,level)    #mundur, tengok kanan    turtle.backward(l)    turtle.right(sl)    turtle.forward(l*bl/dl)        turtle.backward(l*br/dl)    turtle.right(sr)    turtle.forward(l)    if level<lv:        maju(l,level)            turtle.backward(l)    turtle.left(sr)     turtle.forward(l*br/dl)        level   -= 1    maju(l,2)#agar gambar tak langsung hilangturtle.exitonclick()  `

BBM Crash After Update?

Relax.

Solved, :)

At least at my iPhone 5 with iOS 9.3

Pohon Asimetris, :)

Modifikasi dari kode sebelumnya

```import turtle
import numpy

#buat pola di sini
turtle.shape("turtle")
turtle.left(90)

lv  = 11
l   = 100
sl  = 47
sr  = 17

turtle.penup()
turtle.backward(l)
turtle.pendown()
turtle.forward(l)

def maju(l,level):
l           = 3./4.*l
#turtle.backward(l)
turtle.left(sl)
turtle.forward(l)
level       += 1
if level<lv:
maju(l,level)

turtle.backward(l)
turtle.right(sl)
turtle.right(sr)
turtle.forward(l)
if level    <lv:
maju(l,level)
turtle.backward(l)
turtle.left(sr)
level       -= 1

maju(l,2)

#agar gambar tak langsung hilang
turtle.exitonclick()

```
.

Fractal Tree using Python with Turtle Module

Here is "minus one" nearly symmetrical fractal tree
`import turtleimport numpy#buat pola di sini#kura-kura menghadap ke atasturtle.shape("turtle")turtle.left(90)lv  = 7l   = 100s   = 17turtle.penup()turtle.backward(l)turtle.pendown()turtle.forward(l)def maju(l,level):    l           = 3./4.*l    turtle.left(s)    turtle.forward(l)    if level<lv:        level   +=1        maju(l,level)        turtle.backward(l)    turtle.right(2*s)    turtle.forward(l)    if level<lv:        maju(l,level)    turtle.backward(l)    turtle.left(s)    level       -=1maju(l,2)#agar gambar tak langsung hilangturtle.exitonclick() `
.

if we want symmetrical result, just move
level +=1
syntax
to the place before first if

Some Mistake Often Provide Beautiful Result.

:)

Planned to coding tree branch of tree, fractal mode, using turtle module on python. Has some trouble on backward rule. It become flower, by definition, it's still tree, :)

`import turtle#buat pola di sini#kura-kura menghadap ke atasturtle.shape("turtle")turtle.left(90)s   = 37lv  = 7l   = 100turtle.forward(l)def mundur(l,level):    l   = 4./3.*l    turtle.backward(l)    turtle.right(3*s)    maju(l,level)def maju(l,level):    l   = 3./4.*l    turtle.left(s)    turtle.forward(l)    level   +=1    if level<=lv:        maju(l,level)    else:        mundur(l,level)maju(l,2)#agar gambar tak langsung hilangturtle.exitonclick() `

The Best Ever

Pulang dari kampus

Sampai rumah, buka garasi, masukkan si ducati .

"Ayah pulang"

Dibukakan pintu dalam sama Alfa, diganjal sama barbel kaki biar gak nutup lagi.

"Makasih mas "

Terdengar ketiplak-ketiplak khas kaki adek lari dari belakang

"Ibuk..., ayah pulang"

"Iya" sahut ibuk dari belakang.

Lepas baju, tinggal pake kaos warna kelabu yang  diwajibkan alfa (dia protes kalo ayahnya pake warna selain kelabu dan hitam).

Mau ganti celana jeans dengan celana pendek, eh si adek sudah narik tangan.

"Ayah makan" sambil menuntun ayah ke depan

"Iya"

Di ruang depan sudah ada "tamu" lain untuk teman makan sore a la adek, penguin dan kelinci.

"Iya".

Jadilah acara pertama di rumah diisi dengan menyuapi penguin, walau perut sendiri kelaparan.

Alfa muncul,

Beta yang selalu ikut ajakan mas-nya langsung sigap meninggalkan kelincinya.

"Ayah tunggu ya"

Mereka berdua menghilang ke belakang.

Bengong sendiri,

Mau lihat tv juga paling gak boleh ubah channel sama Alfa, jam segini waktunya Kambu (eh atau Monk, atau Pororo).

Belum semenit merasakan nikmatnya punggung yang beradu dengan sofa

Sayup-sayup terdengar langkah kaki mereka berdua dari belakang, kali ini pelan, hati-hati.

Alfa muncul, disusul Beta di belakang

"Selamat ulang tahun Ayah"

Mereka masing-masing membawa semangkuk puding.

....

"Selamat ulang tahun Yah, semoga..." Ibuk ikut nimbrung.

"Yuk nyanyi sama-sama dulu..."

....

Dan sore itu kami menikmati puding buatan ibuk berempat, di ruang depan.

Puding coklat untuk ayah, ibuk dan Beta

Alfa makan puding pink, warna favoritnya, sendirian, :)

Sore yang menyenangkan
