まあ，考えてみれば当たり前なのですが，Cの，<\/p>\n
for ( i=0; i<10; i++) {\n \u306a\u3093\u3068\u304b\u304b\u3093\u3068\u304b;\n}<\/pre>\nは，Pythonでは，<\/p>\n
for i in range(0,10):\n \u306a\u3093\u3068\u304b\u304b\u3093\u3068\u304b<\/pre>\nに置き換わります．<\/p>\n
ただし，iの最終値を利用する場合，Cの例では，i == 10 になっているのに対して，Pythonの例では，i == 9 です．<\/p>\n
for ループの中で条件によってループを抜け出す工夫をした場合，抜け出さないままループを完了した時，iの値が異なるわけです．<\/p>\n
これを避けるには，<\/p>\n
i = 0\nwhile i < 10:\n \u306a\u3093\u3068\u304b\n \u6761\u4ef6\u306b\u3088\u3063\u3066\u5206\u5c90\n \u304b\u3093\u3068\u304b\n i += 1<\/pre>\nとしないといけません．<\/p>\n
他の人が書いたCのソースをpythonにコンバートするような時には注意が必要です．<\/p>\n","protected":false},"excerpt":{"rendered":"
