如何用单行语句替代多条Robot Framework的Replace String命令？

以下是Robot Framework中的多条字符串替换操作：

${rowNum}    Convert To String    ${iRowNum}
${ScheduledJobManager_T1_Col_1_Row_i}    Replace String    ${ScheduledJobManager_T1_JobID}    <rowNum>    ${rowNum}
${ScheduledJobManager_T1_Col_3_Row_i}    Replace String    ${ScheduledJobManager_T1_JobName}    <rowNum>    ${rowNum}
${ScheduledJobManager_T1_Col_5_Row_i}    Replace String    ${ScheduledJobManager_T1_CreatedBy}    <rowNum>    ${rowNum}
${ScheduledJobManager_T1_Col_10_Row_i}    Replace String    ${ScheduledJobManager_T1_ViewDetails}    <rowNum>    ${rowNum}

提问：上述多次使用Replace String的操作是否可以整合为单行语句？

可以整合，但原生Replace String关键字本身是单条执行的，没法直接把多个替换写在一行，不过可以通过两种方式实现批量处理，减少重复代码：

1. 自定义封装关键字（推荐，可读性高） #

把重复的替换逻辑封装成一个自定义关键字，只需调用一次就能完成所有替换：

*** Keywords ***
Batch Replace RowNum Placeholder
    [Arguments]    @{var_pairs}
    :FOR    ${source_var}    ${target_var}    IN    @{var_pairs}
    \    ${source_var}    Replace String    ${target_var}    <rowNum>    ${rowNum}

*** Test Cases ***
YourTestCase
    ${rowNum}    Convert To String    ${iRowNum}
    Batch Replace RowNum Placeholder
    ...    ${ScheduledJobManager_T1_Col_1_Row_i}    ${ScheduledJobManager_T1_JobID}
    ...    ${ScheduledJobManager_T1_Col_3_Row_i}    ${ScheduledJobManager_T1_JobName}
    ...    ${ScheduledJobManager_T1_Col_5_Row_i}    ${ScheduledJobManager_T1_CreatedBy}
    ...    ${ScheduledJobManager_T1_Col_10_Row_i}    ${ScheduledJobManager_T1_ViewDetails}

2. 用Evaluate结合Python表达式（紧凑写法） #

借助Evaluate关键字调用Python的字典推导式，一次性完成所有替换，不过可读性稍弱：

${rowNum}    Convert To String    ${iRowNum}
${replace_pairs}=    Create Dictionary
...    ${ScheduledJobManager_T1_JobID}=${ScheduledJobManager_T1_Col_1_Row_i}
...    ${ScheduledJobManager_T1_JobName}=${ScheduledJobManager_T1_Col_3_Row_i}
...    ${ScheduledJobManager_T1_CreatedBy}=${ScheduledJobManager_T1_Col_5_Row_i}
...    ${ScheduledJobManager_T1_ViewDetails}=${ScheduledJobManager_T1_Col_10_Row_i}
${updated_vars}=    Evaluate    {k: v.replace('<rowNum>', "${rowNum}") for k, v in ${replace_pairs}.items()}

之后可以通过${updated_vars}[${ScheduledJobManager_T1_JobID}]这类方式获取替换后的变量值。
