### 获取变量的对象名称

    from mymodule import MyObject

    def return_string():
        return "Hello, world!"

    def return_object(name):
        return MyObject(name)
</nbsp>

    *** Test Cases ***
    Returning one value
        ${string} =    Return String
        Should Be Equal    ${string}    Hello, world!
        ${object} =    Return Object    Robot
        Should Be Equal    ${object.name}    Robot

### 字符串和数字变量
RobotFramework的案例数据缺省都是字符串，而`${}`中的内容是由Python解释执行的，所以`${1}`是数字1，`1`是字符串“1”。

     String and Number
        ${str1} =    Set Variable    1
        ${str2} =    Set Variable    2
        ${num1} =    Convert to Integer    1
        ${num2} =    Convert to Integer    2
        Should Not Be Equal    ${str1}    ${num1}
        Should Not Be Equal    1    ${num1}
        Should Be Equal    1+1    ${num1}+1
        Should Not Be Equal    1+1    ${num2}
        Should Not Be Equal    1+1    ${str2}
        Should Be Equal    ${num1+1}    ${num2}
        Should Be Equal    ${num1+1}    ${2}
        Should Be Equal    ${1+1}    ${num2}
        Should Be Equal as Strings    ${str1}    ${num1}

### 数组变量

    *** Test Cases ***
    List Variables
        @{list} =    Set Variable    first value    second value
        Should Be Equal    @{list}[0]    first value
        Should Be Equal    ${list[0]}    first value
        Should Be Equal    @{list}[1]    second value
        Should Be Equal    ${list[1]}    second value
        ${index} =    Set Variable    ${2}
        Should Be Equal    @{list}[${index - 1}]    second value
        Should Be Equal    @{list}[${${index} - 1}]    second value
        Should Be Equal    ${list[2 - 1]}    second value
        Should Be Equal    ${list[${index} - 1]}    second value
        Should Be Equal    ${list[${index - 1}]}    second value
