My application has a large array of objects, which I stringify and save them to the disk. Unfortunately, when the objects in the array are manipulated, and sometimes replaced, the properties on the objects are listed in different orders (their creation order?).

Which simplifies to:
f(b) = f(a-1) ^ (a ^ a+1 ^ a+2 .. ^ b)
f(b) = f(a-...

How to deal with SettingWithCopyWarning in Pandas?

The SettingWithCopyWarning was created to flag potentially confusing "chained" assignments, such as the following, which does not always work as expected, particularly when the first selection returns a copy. [see GH5390 and GH5597 for background discussion.]
