机器人框架中的 for 循环字典 [英] For loop over dictionary in Robot Framework

问题描述

是否有正确的方法在 RF 中循环字典?我使用pythonic方式，但失败了:

Is there a proper way to loop over a dictionary in RF? I used pythonic way, but failed:

:FOR  ${key}  ${value}  IN  &{dict}

输出:FOR 循环值的数量应该是其变量的倍数.有 2 个变量，但有 1 个值.

output: Number of FOR loop values should be multiple of its variables. Got 2 variables but 1 value.

同样，当我将字典指向标量变量时.不过，我在文档中找不到示例.有人解决了吗?

Same, when i pointed dictionary as scalar variable. I couldn't find an example in documentation though. Has anyone solved that?

附言

我知道您使用 kw 的解决方法.获取字典键和获取字典值，然后使用 Set To Dictionary ${key} ${new_value} 更新值，但这似乎对人类不友好，并且使用了多个 for 循环迭代而不是一个.

I am aware of workaround solution, that you use kw. Get Dictionary Keys and Get Dictionary Values, then, to update values you use Set To Dictionary ${key} ${new_value}, but this seems to be human unfriendly and uses several for loops iterations instead one.

推荐答案

Loop Through Dict
    &{mydict}    Create Dictionary    a=1    b=2
    :FOR    ${key}    IN    @{mydict.keys()}
    \    Log    ${mydict["${key}"]}

Loop Through Dict And Multiplicate Values
    &{mydict}    Create Dictionary    a=1    b=2
    :FOR    ${key}    IN    @{mydict.keys()}
    \    ${new_value}    Evaluate    ${mydict["${key}"]}*2
    \    Set To Dictionary   ${mydict}    ${key}=${new_value}
    Log    ${mydict}
