这段代码的可视化执行在autbor.com/addingloopfixed进行。 我们的for循环遍历了clothes列表中的条目,但是没有修改循环内部的clothes。而是改了一个单独的列表,newClothes。然后,在循环之后,我们通过用newClothes的内容扩展来修改clothes。你现在有了一个匹配袜子的clothes列表。 同样,你不应该在遍历列表时删除列表中的条目。

# Loop over fixed length blocks while (block := f.read(256)) != '': process(block) 或者出现于列表推导式中,在筛选条件中计算一个值,而同一个值又在表达式中需要被使用: [clean_name.title() for name in names if (clean_name := normalize('NFC', name)) in allowed_names] ...
For example, if the server is a 2-socket machine with two k-groups, only processors from the first k-group are used for the R processes. The same limitation applies when you configure resource governance for R script jobs. This issue is fixed in SQL Server 2016 (13.x) Service ...
However, if you continue using , you'll see that your application just continues to the next loop: If you want to concentrate on your own code, use the Step Into My Code button . Thus you'll avoid stepping into library classes. For more information, refer to Stepping toolbar and Step ...
