Below code demonstrates the difference between assignment, shallow copy using the copy method, shallow copy using the (slice) [:] and the deepcopy. Below example uses nested lists there by making the differences more evident.
A shallow copy constructs a new compound object and then (to the extent possible) inserts references into it to the objects found in the original. A deep copy constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original.
To get a fully independent copy of an object you can use the copy.deepcopy() function. For more details about shallow and deep copying please refer to the other answers to this question and the nice explanation in this answer to a related question.
When selecting a sub dataframe from a parent dataframe, I noticed that some programmers make a copy of the data frame using the .copy() method. For example, X = my_dataframe[features_list].copy() ...
I am working with two files, and I need to copy a few lines from one file and paste them into another file. I know how to copy (yy) and paste (p) in the same file. But that doesn't work for different
Create a copy constructor: class DummyBean { private String dummy; public DummyBean(DummyBean another) { this.dummy = another.dummy; // you can access } } Every object has also a clone method which can be used to copy the object, but don't use it. It's way too easy to create a class and do improper clone method. If you are going to do that, read at least what Joshua Bloch has to say about it ...
You should check the ADD and COPY documentation for a more detailed description of their behaviors, but in a nutshell, the major difference is that ADD can do more than COPY: ADD allows <src> to be a URL Referring to comments below, the ADD documentation states that: If is a local tar archive in a recognized compression format (identity, gzip, bzip2 or xz) then it is unpacked as a directory ...
So, in order to access that directory and copy the content inside it, your final build (third instruction) is copying from that directory using --from=publish so you can access the directory from the previous build.
To copy a directory's content to another directory you CAN use ansibles copy module: - name: Copy content of directory 'files' ansible.builtin.copy: src: files/ # note the '/' <-- !!! dest: /tmp/files/ From the docs about the src parameter: If [src] path is a directory, it is copied recursively. In this case, if path ends with /, only inside contents of that directory are copied to destination ...
If you want a copy, the fastest way of doing this would be to save the project. Then make a copy of the entire thing on the File System. Go back into Visual Studio and open the copy (by right clicking on solution => add existing project => open the copied project). From there, I would most likely recommend re-naming the project/solution (Steps of Safely Renaming Project are in the following ...
