在Robot Framework中，列表变量和包含列表的标量变量之间有什么区别? [英] In Robot Framework, what is the difference between a List Variable and a Scalar Variable containing a list?

问题描述

在Robot Framework中，我们可以将列表分配给标量变量或列表变量，如下所示:

In Robot Framework, we can assign a list to a Scalar Variable or to a List Variable, as shown below:

| @{list} =   | Create List | a | b | c |
| ${scalar} = | Create List | a | b | c |

列表变量和包含列表的标量变量之间有什么区别?

What is the difference between a List Variable and a Scalar Variable containing a list?

推荐答案

如果您的问题中显示了作业，则没有区别.如果您将每个日志记录下来，您将获得完全相同的输出.

In case of the assignment shown in your question, there is no difference. If you log each of those you'll get the exact same output.

注意:此功能已在2.8版中引入(请参见

Note: this functionality was introduced in version 2.8 (see Using scalar variables as lists in Robot Framework User's Guide).

使用这些值时会有所不同.当您使用@符号引用列表时，列表中的每个元素都将成为一个单元格.在下面的示例中，以下三行给出相同的结果:

The difference comes when you use the values. When you use the @ symbol to reference a list, each of the elements in the list becomes a cell. In the following example, the following three lines give identical results:

| | A keyword that expects three arguments | a | b | c
| | A keyword that expects three arguments | @{list}
| | A keyword that expects three arguments | @{scalar}
