机器人框架工作迭代列表问题

Question

嗨，我试图遍历列表，并在字符串中使用列表中的每个元素。 但整个列表将被复制到字符串中，而不是逐个元素。 我的测试用例和日志如下，请帮忙。

test
    ${list}    Create List    first
    : FOR    ${i}    IN RANGE    1    17
    \    log    ${i}
    \    Append To List    ${list}    ${i}
    log    ${list}
    :FOR    ${i}    IN    ${list}
    \    log    show:all interfaces-state interface "gfast 0/${i}"

LOG

你需要迭代这样的列表:FOR ${i} IN @{list}
