Pythonを使用してパッチワークパターンを描画するタスクが与えられました。ユーザーから幅と高さを取得する必要があります。どちらも3色より大きく10色未満で、4色である必要があります。同じ色にすることはできません。私はその罰金のためのコードを書きました。しかし、私は2つの異なるタイプのパターンを描く必要があります。1つのパターンはすべてエッジに沿っており、パッチの深さは1つだけで、2番目のパターンは中央の正方形を塗りつぶします。さて、これを描くために使用したコードは、最初のパッチを上、下、そして各側に沿って繰り返し、次に2番目のパターンを中央全体に繰り返します。しかし今、私はそれぞれの異なるパッチに色を割り当て、与えられた色を循環して、最初の色から始まり、それらすべてを循環し、最初の色から再び始まるようにする必要があります。

私の質問は、順序が行ごとに異なるため、色を循環させる方法がわからないということです。私がこれまでに書いたものでそれを行うための良い効率的な方法はありますか？個々のパッチを描画し、それを線上で繰り返します。もしそうなら、最良の方法は何ですか？

あなたはitertools.cycle繰り返しすべての色を通過するために使用することができます。したがって、すべてのパッチがと呼ばれるリストにあるとpatchesしましょう。次のようなことができます。

import itertools
colors = ['red','blue','green','yellow']
patches = ['a','b','c','d','e','f','g','h','i','j']

for patch, color in itertools.izip(patches, itertools.cycle(colors)):
    # color a patch
    print 'Colour', patch, 'as', color

プリントアウト

Colour a as red
Colour b as blue
Colour c as green
Colour d as yellow
Colour e as red
Colour f as blue
Colour g as green
Colour h as yellow
Colour i as red
Colour j as blue

私はあなたがこのようなことをすることを提案します：

for x in range(0,maxX-1):
   for y in range(0,maxY-1):
      paint_patch(x,y,color((x+y)%4)

基本的に、これは各行を異なる色で開始し、それらを循環します。対角線もきれいになります。
