Detailed Description
式オブジェクト Python式を書けばPython ASTの式が構築できるオブジェクト builder = Builder() a = builder.literal(3) b = builder.literal(4) c = a+b とすると、変数'c'は "3+4" を表現するPython ASTになる 大体の場合にうまくいくように見えるが、いくつか注意点がある 1. 左辺値にPython ASTを持ってくること メソッドが呼ばれるのは左辺値なので、 builder = Builder() a = builder.literal(3) b = 4 c = a+b これはうまくいくが、 builder = Builder() a = 3 b = builder.literal(4) c = a+b これはうまくいかない 2. 比較演算ができない Python AST式オブジェクトに'=='を適用した場合、 返すオブジェクトは、比較式を表現するオブジェクトであり、比較結果ではない builder = Builder() a = builder.literal(4) b = builder.literal(100) c = (a == b) if c: print 'xx' c が指すオブジェクトは '4 == 100' というPython ASTであり、True, Falseではない (なので、条件は常に真である)
