如何将变量写入文件？

Question

我想将${Username}值存储在输出文件中：

E.g.如果${Username}等于0401190926729000，则此值将存储在文件中。

这里有一个建议：

*** Settings *** 
Library OperatingSystem 
Library String 

*** test cases *** 
write_variable_in_file 
    ${Username} = Generate Random String 1 abc 
    log to console ${Username} 
    run keyword if '${Username}' == 'a' write_variable_in_file ${Username} 

*** Keywords *** 
write_variable_in_file 
    [Arguments] ${variable} 
    Create File ${EXECDIR}/file_with_variable.txt ${variable}
