【问题描述】：

我将一些输出拆分为一个列表，然后我试图清理该列表，因为列表中有一些我不需要的值。我想删除任何不是节点或日期的列表项；但是，Remove Values From List 关键字会返回一个空列表。任何建议将不胜感激。

Create And Clean Times List   
    @{times}    Split String    ${output}       separator=${\n}
    Log List    ${times}
    ${value}=   Set Variable     @{times}[0]
    @{times2}=  Remove Values From List    ${value}
    Log List    ${times2}

【解决方案1】：

Remove values from list 不会返回新列表，它会从原始列表中删除值。

这是一个说明：

*** Settings ***
Library  Collections

*** Variables ***
@{full_list}   one  two  three
@{short_list}  one  three

*** Test Cases ***
Example
    ${result}=  remove values from list  ${full_list}  two
    should be equal  ${result}  ${NONE}
    should be equal  ${full_list}  ${short_list}
