  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}

  迭代字典's keys, you don' t必须使用任何python方法，但insted使用Robotframework的 @ 修饰符进行列表扩展 . 例如：

  ${mydict}    Create Dictionary    a=1    b=2
  :FOR    ${key}    IN    @{mydict}
  \    Log     The current key is: ${key}
  # there are at least to ways to get the value for that key
  # "Extended variable syntax", e.g. direct access:
  \    Log     The value is: ${mydict['${key}']}
  # or using a keyword from the Collections library:
  \    ${value}=    Get From Dictionary    ${mydict}    ${key}
  \    Log     The value through Collections is: ${value}
  

  键上的循环直接工作，因为在python中，字典的 list() 演员实际上是其键的列表 . 示例代码：

  mydict = {'a': 1, 'b': 2}
  print(list(mydict))
  # the output is 
  # ['a', 'b']

  有一个python的dict方法 items() 迭代字典并返回一个key，value的元组 . 它可以用来快速地将它们两个放在远离计算机的Robotframework 's loop - but I'm中，并且无法看到它是否在它中工作（据说是的）：

  ${mydict}    Create Dictionary    a=1    b=2
  :FOR    ${key}    ${value}    IN    @{mydict.items()}
  \    Log     The current key is: ${key}
  \    Log     The value is: ${value}

  检查方案：

  :FOR    ${key}    IN    @{mydict}
  # works as @{mydict.keys()}
  
  :FOR    ${key}    ${value}    IN    @{mydict.items()}
  # doesn't work at all
  

  找到另一种解决方案：

  :FOR    ${key}     ${value}    IN ZIP    ${mydict.keys()}    ${mydict.values()}
  
  # And another less readable (can work without setters)
  :FOR    ${el}    IN    @{mydict.items()}   
  \    ${key}=    Set Variable    ${el[0]}
  \    ${value}=    Set Variable    ${el[1]}

  另一种解决方法是在for循环期间使用关键字“Get From Dictionary” .

  Loop through and Log key and value in dict
      [Documentation]    Loops through each key and stores the key value 
      ...                in a variable that can be used during the for 
      ...                loop, as if you were iterating through python 
      ...                with "for key, value in dict.iteritems()".
      &{mydict}    Create Dictionary    a=1    b=2
      :FOR    ${key}    IN    @{mydict.keys()}
      \    ${value}=    Get From Dictionary    ${mydict}    ${key}
      \    Log    ${key}, ${value}
