其实python和ruby非常接近,比大多数别的语言要接近的多,所以喜欢用啥就用啥(大实话,虽然也是废话)。语法上的差别虽然有那么一点,大部分是syntax sugar,我斗胆稍微列几个(python我也忘得差不多了,不对的大家尽管来鞭尸吧),但是主要差异还是设计思想上的:灵活vs明确. 我不认为两者在生产力上会有什么差别,如果你熟...

在编程中,"Ruby-esque" if else条件语句是指类似于Ruby语言中的条件语句的写法,即在条件表达式后直接跟着代码块,而不需要使用大括号或其他语法元素。这种写法通常被称为"三元运算符"或"条件运算符"。 在Ruby语言中,这种写法如下所示: 代码语言:txt 复制 result = condition ? value_if_true : value_if_false...

使用显式换行符时可能会更明显。您的第一个示例等效于:

If you’re having trouble with updating custom fields, be sure to check the permission of the user that created the custom field. Only text fields can be updated as custom fields. At this point it isn’t clear what to send the Zoho API to have it accept anything else. Please send in...
