如何在某些方法中将字典作为参数传递，该方法将从该方法中动态获取所有用户并执行所需的操作？

Question

我遇到了一个问题，我必须将字典（或其他一些数据存储数据类型）作为参数传递给某个方法，该方法将从该方法中动态获取所有用户并执行所需的操作。我的问题是：

1) 在机器人框架中可以吗？

2）如果可能的话，我们将如何做到这一点？

Adding Participant
...  Number_of_users= depend on participants name
...  Participant name= x, y, z, etc..


Adding Participant 
  [Arguments]  ${Number_of_users}  ${Participant name}
  :FOR    ${ELEMENT}    IN   ${Participant name} -->  [How this participant name will be stored dynamically ?]
  \    Log    ${ELEMENT}
  \    Run Keyword  ${ELEMENT} {?{?{?{It will do some operations for user x then in next loop y and so on}}}

如何将字典作为关键字参数传递？- 与任何其他数据类型相同。在下面的示例中，您可以看到这一点，以及两种迭代（循环）字典键的简单方法：

*** Test Cases ***
A case
    ${a dict}=    Create Dictionary     key1=value1    key2=another value
    My Keyword That Works With Dictionaries    ${a dict}

*** Keywords ***
My Keyword That Works With Dictionaries
[Arguments]     ${dct}

    ${the type}=    Evaluate    type($dct)
    Log To Console  The passed argument is of type ${the type}    # will print dict

    ${all keys in the dict}=    Get Dictionary Keys    ${dct}   # a list will all dictionary keys

    # 1st way to iterate/loop
    :FOR   ${key}    IN    @{all keys in the dict}
    \    Log To Console   Working with key ${key}
    \    ${value}=     Get From Dictionary   ${dct}    ${key}
    \    Log To Console   Its value is "${value}" (another way to get it is ${dct['${key}']})

    # the 2nd way
    :FOR   ${key}    IN    @{dct}  
    # this comes from the python's syntax "for key in dct:" - an 
    # iterator over a dictionary returns its keys
    \    Log To Console   Working with key ${key}
    # and so on
