QUESTION
In Python, is there a way to distinguish between strings and other iterables of strings?
A str
is valid as an Iterable[str]
type, but that may not be the correct input for a function. For example, in this trivial example that is intended to operate on sequences of filenames:
ANSWER
Answered 2022-Mar-29 at 06:36This issue has been discussed since at least July 2016. On a proposal to distinguish between str
and Iterable[str]
, Guido van Rossum writes:
Since

this is tricky. Various proposals have been made but they don't fit easily in the type system.
You'll need to list out all of the types that you want your functions to accept explicitly, using Union
(pre-3.10) or |
(3.10 and higher).
e.g. For pre-3.10, use:

It doesn't appear doable in safe Rust, at least not with reasonable algorithmic complexity. (See Aiden4's answer for a solution that does it by re-building the whole map.)
But if you're allowed to use unsafe, and if you're determined enough that you want to delve into it, this code could do it:
QUESTION
I have a list of points where each point is a tiny list of size 2
. I want to sort the list of points in increasing order of x
and if x
values are equal, I break tie by sorting in decreasing order of y
.
I wrote a custom comparator to sort the points like this:
...ANSWER
Answered 2022-Mar-05 at 23:55I am missing something trivial
Method equals()
should be used for object comparison. Double equals ==
checks whether two references point to the same object in memory.
If you change the condition inside the comparator to !a.get(0).equals(b.get(0))
it will work correctly.
However, (10001, -10) was put before (10001, -8). Even though -8 is larger than -10.
The reason for such behavior is that JVM caches all the instances of Integer
(as well as Byte
, Short
and Long
) in the range [-128; 127]
. I.e. these instances are reused, the result of autoboxing of let's say int
with a value of 12
will be always the same object.
Because small values in your example like 3
, 5
, 12
will be represented by a single object, they were compared with ==
without issues. But the result of comparison with ==
for two Integer
instances with a value of 10001
will be false
because in this case there will be two distinct objects in the heap.
The approach of caching frequently used objects is called the Flyweight design pattern. It's very rarely used in Java because this pattern can bring benefits when tons of identical objects are being created and destroyed. Only in such a case caching these objects will pay off with a significant performance improvement. As far as I know, it's used in game development.
Use the power of objectsPoint
must be an object, not a list, as Code-Apprentice has pointed out in his answer. Use the power of objects and don't overuse collections. It brings several advantages:
- class provides you a structure, it's easier to organize your code when you are thinking in terms of objects;
- behavior declared inside a class is reusable and easier to test;
- with classes, you can use the power of polymorphism.
Caution: objects could be also misused, one of the possible indicators of that is when a class doesn't declare any behavior apart from getters and its data is being processed somehow in the code outside this class.
Although the notion of point (as a geometrical object) isn't complicated, there are some useful options with regard to methods. For example, you could make instances of the Point
class to be able to check to whether they are aligned horizontally or vertically, or whether two points are within a particular radius. And Point
class can implement Comparable
interface so that points will be able to compare themselves without a Comparator
.
With Java 8 method sort()
was added to the List
interface. It expects an instance of Comparator
, and if element of the list implement comparable, and you want them to be sorted according to the natural order null
can be passed as an argument.
If the specified comparator is null then all elements in this list must implement the Comparable interface and the elements' natural ordering should be used.
So instead of using utility class Collections
you can invoke method sort()
directly on a list of points (assuming that Point
implements Comparable
):

I need help to make the snippet below. I need to merge two files and performs computation on matched lines

I need to to update the oldFile.txt based on the data in the newFile.txt and compute the changes in percentage. Any idea will be very helpful. Thanks in advance

I use the formula below to calculate pct change.
percentage_change = 100*(new-old)/old
If old is 0 it is changed to 1 to avoid division by zero error.

dict
keeps insertion order since Python 3.6 (see this).
OrderedDict
was developed just for this purpose (before Python 3.6).
Since Python 3.6, is the key order always the same for dict
or OrderedDict

I wonder whether I can do this in my code and have always the same behavior (except of equality, and some extended methods in OrderedDict
) but more efficiently:

I was checking the code of the toolz library's groupby
function in Python and I found this:
ANSWER
Answered 2021-Sep-22 at 13:05This is a somewhat confusing trick to save a small amount of time:
We are creating a defaultdict
with a factory function that returns a bound append
method of a new list instance with [].append
. Then we can just do d[key(item)](item)
instead of d[key(item)].append(item)
like we would have if we create a defaultdict
that contains lists. If we don't lookup append
everytime, we gain a small amount of time.
But now the dict
contains bound methods instead of the lists, so we have to get the original list instance back via __self__
.
__self__
is an attribute described for instance methods that returns the original instance. You can verify that with this for example:

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
