![]() TaskName field set to Name1 dynamic content of the "Get items" action, Executor Claims field set to Person1 dynamic content of the "Get items" action as a custom value, the Due Date field set to Date1 dynamic content of the "Get items" action. Within "Apply to each" action, add a "Create item" action, specify Site Address and List Name set to List A ( List 1).First: Copying by Slicing The most common way (especially in python2) to copy a python list is to use slicing. The first two methods can be used in python2 and python3 whereas the third one works for python3 only. Add a "Apply to each" action, input parameter set to output of "Get items" action. In this article, we will discuss three different methods to copy a python list.Add a "Get items" action, specify Site Address and List Name set to List B ( List 2).Add a proper trigger, here I use Flow Button trigger.I have made a test on my side and please take a try with the following workaround: In addition, if you want to copy a text value ( Person1) from List 2 into a Person or Group type column ( Executor) within List 1, you should fill the email address of the person within the text column ( Person1) of the List 1. Note: The Name1 and Person1 are both Single line of text type column, the Date1 is Date type column. Note: The TaskName column is a Single line of text type column, the Executor column is a Person or Group type column and the Due Date column is a Date type column. I have created two SharePoint lists on my side and the data structure of it as below: If you are using python3, use the listâs copy() method.You please share a screenshot of your flow's configuration?Ĭould you please share more details about your two SharePoint lists (List 1 and List 2)? If you are using python2, you can copy a list by slicing or by using the list() function. The only downside is that it is not available in python2.Ä«ut if you are using python3, there is no debate this is the best, and most readable way to copy a list. Python3 introduced a new method to lists called copy() and it does exactly what you think it does. This is when Python3 comes to the rescue with a beautiful way to copy a list. > a = Ä®ven though this is not a common way to copy a list, it is still a valid one. > s = "hello"Ä«ut since a list is an iterable itself, there is nothing that prevents you from creating a list from another list. The list() function is used to create a list object from any iterable.Īnd most of the time in real code, this iterable is not a list.įor example, the following code creates a new list off of the items of a string. Second: Copying using list() functionĪnother way to create a copy of a list is to use the list() built-in function. > a = Īs you can see, after a was modified, b remains unchanged.Īwesome, we successfully copied a python list. If b remains unchanged, then a and b refer to two separate objects. ![]() If b is modified, then a and b refer to the same object. List copy using (assignment operator) This is the simplest method of cloning a list by using operators. Letâs try to modify a and see if b remains unchanged. Original List: 4, 8, 2, 10, 15, 18 After Cloning: 4, 8, 2, 10, 15, 18 3. Using Enumerable.ToList Method (System.Linq) Using List.CopyTo Method.It is very simple to do if you see our examples. In this blog, we will use 3 different methods to clone or copy a list. Otherwise, they refer to different objects. We can easily clone or copy a list to another list or array in C. Needless to say, two variables will refer to the same object only if the id of these two variable are exactly the same. If you donât know what the id() function does, it basically returns the address of a python object in the memory. ![]() One way is by observing that id(a) is different from id(b). > a = Ä¡- the items of list b are the same as those of list a When you omit the start index and the end index from the slice, then your slice will start from the beginning of the list all the way to the end of the list.Īnd because slicing creates a new object, then the above code effectively copies or clones the whole list into another list. If you have been coding in python for a while, you probably came across some code that looks like this. The most common way (especially in python2) to copy a python list is to use slicing. In this article, we will discuss three different methods to copy a python list. The following figure shows what we want to achieve when we copy or clone a list. > a = 10Īs you can see, changing the value of a also changes the value of b because they both refer to the same list object.Ĭopying a python list means creating a new python object whose contents are identical. Letâs check what happens to b when we modify a. Letâs take a look at this example > a = Ä« is in fact a, they both refer to the same python object. There are many ways to copy a python list.Ä«ut first, letâs talk about what copying a list actually means.
