Problem: When creating a dictionary, you can also control the order of elements in the dictionary while iterating or serializing it;Solution: You can use the Ordereddict class in the Collections module to control the order of elements in the dictionary. When the dictionary is iterated, he is strictly in the order in wh

currently traversing ht[1], then the iterator iterates through the elements of the number 4th bucket of ht[1] (original ht[0]), and the traversal process ends, while there are actually some elements that are not traversed.As you can see from the above discussion, rehash cannot be allowed during traversal.As you can see from the above discussion, using a security iterator, as long as there is no action to delete the element, the traversal process is basically no problem, and the elements that al

In the actual working environment, if you Truncate several data dictionary tables in the database during operation, the database will no longer be available, this article will give a detailed explanation of a related case. The example is as follows: Database environment: Oracle Database 9.2.0.7 RAC. (Note: the database is not backed up because the transaction volume of the database is large ). Truncated tab
