如何在Robot框架（浏览器库）中从字符串中获取数值

Question

我将尝试从按钮的 id 中获取字符串。它将是“username12”，我需要获取该 12 数字值。 它将使用

get text

存储，但那是字符串，我需要数值。

    ${no}=    Get Trailing Number   ${username}
    Log To Console    no is set to "${no}"


*** Keywords ***
Get Trailing Number
  [Arguments]   ${username}
  ${return_value}   Set Variable    ${NONE}
  TRY
    # Get all trailing digits via regular expression and convert to integer
    ${return_value}=    Evaluate    int(re.search("\\d+$","${username}")[0])     modules=re
  EXCEPT
    Log To Console    No number found
  END

  RETURN    ${return_value}
