赋值语句

At a minimum, it is nearly always a good idea to use braces after an if when the statement in the body is anything other than a simple expression statement, such as an assignment or output expression.

至少，无论 if后面是简单语句，例如赋值和输出语句，还是其他任意语句，使用花括号都是一个比较好的做法。

Assignment is a statement, so it cannot fit into an expression, which is necessary for conditions of if and while statements.

赋值是一个语句，所以它不适合一个表达式，这对if和while语句是一个必要条件。

A qualified name used on the left of an assignment statement binds a name into a specified namespace--either to the attributes of an object, or to the namespace of a module/package, for example

在赋值语句左边出现的受限名字将一个名字绑定到一个指定的名字空间——可能是对象的属性，或是模块/包的名字空间，比如

This is compiled using the principle of means to carry out the assignment of the translation process.

详细说明：这是采用编译原理的方法来进行的赋值语句的翻译程序。

Because SBB is going to set EAX either to zero or to 0xffffffff, we can consider the following AND instruction to be similar to a conditional assignment instruction (much like the CMOV instruction discussed later).

我们先从"与"指令说起，因为根据减法的结果，SBB将eax寄存器设为全F或全0，我们可以推出逻辑"与"的结果等价与一个条件赋值语句(类似于我们后面会讨论的CMOV指令)。

On the other hand, the second assignment is fine.

另一方面，第二个赋值语句则是正确的。

More precisely, all variableassignments in a function store the value in the local symbol table;whereas variable references first look in the local symbol table, thenin the global symbol table, and then in the table of built-in names.thus, global variables cannot be directly assigned a value within afunction (unless named in a global statement), althoughthey may be referenced.

所有的局部变量都存储在这个局部符号表中。引用参数时，会先从局部符号表中查找，然后是全局符号表，然后是内置命名表。因此，全局参数虽然可以被引用，但它们不能在函数中直接赋值（除非它们用global 语句命名）。

However, Python also lets you use several targets (variables, indexings, etc.), separated by commas, on an assignment's lefthand side.

然而，python也让你在赋值语句的左边，使用几个用逗号分开的对象。

Slicings may be used as expressions or as targets in assignment or del statements.

片断可以作为表达式使用，或者是赋值和del语句的目标。

Slicings may be used as expressions or as targets in assignment or del statements.

片断可以作为表达式使用，也可以作为赋值和 del 语句的目标。
