If there is more than one format in the string, you need to pass a tuple as right operand, as in this example.
如果有超过一个的字符串要格式化为一体，就需要将它们传入一个元组做为右值，如下所示。
The left operand is a string expression, and the right operand is a string containing the pattern to be used for matching.
左侧操作数为字符串表达式，右侧操作数为包含匹配所用模式的字符串。
Unlike most other operators, the right operand of the dot (". ") operator is not an object or value; it is the name of a member.
与大多数其他操作符不同，点操作符（“。”）的右操作数不是对象或值，而是成员的名字。
The string format operation involves the processing of the FormatString, looking for format specification sequences, and using these sequences to format the associated data from the right operand.
字符串格式操作涉及处理FormatString、寻找格式定义序列和使用这些序列对右边的操作数中的相关数据应用格式。
Click the icon to the right of the last operand?, select enter text, then enter 1.
单击最后一个operand ？右侧的图标，选择Entertext，然后输入1。
Additional assignment operators that differ by the type of the right-hand operand can be defined for a class type.
可以为一个类定义许多附加的赋值操作符，这些赋值操作符会因右操作符类型不同而不同。
When we use a member function as the right-hand operand of the dot operator, we usually do so to call that function.
通常使用成员函数作为点操作符的右操作数来调用成员函数。
The dot operator fetches its right-hand operand from its left.
点操作符通过它的左操作数取得右操作数。
SFE accepts a single operand to its right. The operand must be the name of a relocatable segment.
SFE在其右边接收一个操作数。操作数必须是一个可重定位段的段名。
The dot operator applies only to objects of class type: the left-hand operand must be an object of class type; the right-hand operand must name a member of that type.
点操作符仅应用于类类型的对象：左操作数必须是类类型的对象，右操作数必须指定该类型的成员。
