一、BuiltIn库中比较重要的关键字
1. Evaluate关键字
如果你需要进行一些数值运算并得到结果，你就需要用到Evaluate关键字。Evaluate会把你想要计算的表达式直接传递给Python，并把Python的计算结果返回给你。这是最经常要用到的，自动导入无需import
2. Should 系列关键字：
Should系列关键字是Should大头的一系列关键字 Should Be Empty · Should Be Equal · Should Be Equal As Integers · Should Be Equal As Numbers · Should Be Equal As Strings · Should Be True · Should Contain · Should Contain X Times· Should End With · Should Match · Should Match Regexp · Should Not Be Empty · Should Not Be Equal · Should Not Be Equal As Integers · Should Not Be Equal As Numbers · Should Not Be Equal As Strings · Should Not Be True · Should Not Contain · Should Not End With · Should Not Match ·Should Not Match Regexp · Should Not Start With · Should Start With
3. Convert To系列关键字： Convert To Binary · Convert To Boolean · Convert To Hex · Convert To Integer · Convert To Number · Convert To Octal · Convert To String 做类型转换比不可少。
4. Run keyword系列关键字： Run Keyword If · Run Keyword If All Critical Tests Passed · Run Keyword If All Tests Passed · Run Keyword If Any Critical Tests Failed ·Run Keyword If Any Tests Failed · Run Keyword If Test Failed · Run Keyword If Test Passed · Run Keyword If Timeout Occurred ·
这些关键字能根据一个判断条件的真假来看是否执行关键字。一般使用这些关键字来实现高级语言中的if else功能。最常用的是Run Keyword If 和 Run Keyword unless 他们俩实现的效果正好相反
5. Exit For Loop关键字： 用作退出循环，一般和Run keyword if 关键字联合使用，来实现条件退出
