Every time a pointer reference is modified , such as through an assignment statement , or when a reference goes out of scope , the compiler must generate code to update the referenced object s reference count 每次修改指针引用时(比如通过赋值语句) ,或者当引用超出范围时,编译器必须生成代码以更新引用的对象的引用计数。
An assignment statement evaluates the expression list ( remember that this can be a single expression or a comma - separated list , the latter yielding a tuple ) and assigns the single resulting object to each of the target lists , from left to right 一个赋值语句对表达式序列求值(还记得这可以是单个表达式或者一个逗号分隔的序列,后者导出一个元组) ,然后从左到右地将对象结果一一地赋给目的序列的每个对象。
An augmented assignment evaluates the target ( which , unlike normal assignment statements , cannot be an unpacking ) and the expression list , performs the binary operation specific to the type of assignment on the two operands , and assigns the result to the original target 一条增量赋值语句对目标(和一般的赋值语句不同,它不能是展开的对象)和表达式列表求值,执行特定于两个操作数的赋值类型的二元运算,并将结果赋值给原先的目标。
Abstract : the objective of this paper was to develop a semiautomatic method for the translation of assignment statements into their corresponding gscct expressions , and thus to facilitate automatic creation of database of generic chemical structures in patents 文摘:本文研究了自然语言处理技术在药物专利检索中的应用,开发出一套翻译软件,能够将药物专利中对族性变量的文本描述半自动化地转化为符合规则的gscct格式,为准确、高效地建立药物专利检索数据库打下了基础
