C # traversal The list and delete one or several elements of the method, your first reaction using what method to implement it? Foreach? ForIf it's foreach, then congratulations, you're wrong. If you're thinking of using for, then you're just a step away from success.the correct approach is to use a for reverse traversal, which is deleted according to the condition . Below we use code to demonstrate foreach

Deletion of the list can cause index changes because of deletion. Use loop traversal directly to delete, only delete 1/2. The remainder cannot be deleted due to indexing problems.
For list traversal elements to be deleted on demand, use iterator.

For the deletion of several elements, you can use a for loo

Set () is a built-in data type "collection type" that is unordered and has a unique value. So the result of the set () is to go to the set and directly away from the duplicated elements, and then list () to return the collection back to the type. However, set () will break the order, and if you want to keep

Paul's classmates had to turn away a few days ago, so how do we remove Paul from the existing list?If Paul's classmates were in the last one, we could delete them using the list pop() method:>>> L = [' Adam ', ' Lisa ', ' Bart ', ' Paul ']>>> L.pop () ' Paul ' >>> print l[' Adam ', ' Lisa ', ' Bart ']The pop () method always deletes the last element of the list,
