1.在Run Keyword If语句中
如果有多个判断语句，可以⽤⼩写 and 或者是 or 连接，具体⽤ and 还是 or 根据⾃⼰程序的情况⽽定
如果判断后要执⾏多个语句
则需要使⽤⼤写 AND 配合 Run Keywords 使⽤
2、不久⼜遇到⼀个问题，我if 条件后⾯需要接多个执⾏语句，还记得当时⾃⼰猜测乱写：run keyword if +条件 log 1 log 2（结果肯定报错
啦），后⾯没办法想出了⼀个解决办法是，把多个执⾏语句封装成⼀个关键字：run keyword if +条件 +封装的关键字。总感觉肯定还有其他
解决办法，就是查不出来，也没问到。终于在⼀个群⾥问到解决⽅法：Run Keyword If 1==1 Run Keywords log 1 AND log 2 。
可以看到⽤到了关键字Run Keywords和AND来处理。

Run keyword if ${2} == ${2}
... Run Keywords Log to console hello world
... AND Keyword1 Pramas1 Params2
... AND Keyword2 Pramas1 Params2
... AND Keyword3 Pramas1 Params2
... AND Keyword3 Pramas1 Params2

Run KeyWord If
使⽤关键字Run Keyword if 务必不要忘记在ELSE前单元格使⽤”…”
Runs the given keyword with the given arguments, if `condition` is true. The given `condition` is evaluated similarly as with `Should Be
True` keyword, and `name` and `*args` have same semantics as with `Run Keyword`.
${status} ${value}= Run Keyword And Ignore Error My Keyword
Run Keyword If ‘${status}’==’PASS’ Some Action arg
Run Keyword Unless ‘${status}’==’PASS’ Another Action My Keyword
If `condition` is a string (e.g. ‘${rc} < 10’), it is evaluated as a Python expression using the built-in ‘eval’ function and the keyword status is
decided based on the result. If a non-string item is given, the status is got directly from its truth value.
由上⽂可知condition会进⾏evaluated，类似于Should Be True这个关键字，其实本质上是调⽤python直接执⾏condition(注意这⼀点，后⾯
我们在写condition条件时可以灵活的使⽤python的⼀些条件表达式写法)：
1.单重条件判断单重条件判断
a.
单⼀条件
${status} Set Variable 1
Run Keyword If ${status} <= 3 log “right”
… ELSE log “error”
b.
多个条件表达式
Run Keyword If ‘${color}’ == ‘Red’ or ‘${size}’ == ‘Small’ or ‘Design’ == ‘Simple’ log “right”
2.多重条件判断多重条件判断( …ELSE IF … ELSE)
${status} Set Variable 1
Run Keyword If ${status} < = 3 log “right”
