There's no need to compare the result of re.search with True. From documentation you can see that search returns a match object when a match is found:

Scan through string looking for the first location where the regular expression pattern produces a match, and return a corresponding match object. Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string.

So, when comparing a match object with True the return is False and your else condition is executed.

Pillow's save method ignores info parameters

ANSWER

Answered 2022-Mar-24 at 10:38

Here is a way of doing what you ask, without using anything external. It inserts a gAMA chunk as follows:

it gets PIL to encode the image into an "in-memory" PNG
it opens the output file on disk in binary mode
it then takes the 8-byte PNG signature created by PIL and writes it to disk
likewise the 25-byte IHDR created by PIL
then it creates a gAMA chunk with your value, prepends the length, appends a CRC and writes to disk
then it copies the remainder of the PIL generated image to disk

Note: The PNG Specification stipulates that the signature must come first, then the IHDR chunk. It also stipulates that gAMA must come before IDAT, so there is no reason my code should create an invalid PNG unless:

PIL suddenly starts generating gAMA chunks, which would lead to multiple such chunks and would be illegal - but we are only doing this precisely because PIL does not write gAMA chunks, or
an unreasonable gamma value is provided, or
some aspect of writing to on-disk PNG fails due to disk full or other I/O error.

I was able to reproduce. This appears to be due to a bug introduced in the png crate version 0.17.4. You don't have to manually manipulate the image and should instead simply use the previous version:

It means your server has different data stored in database: there are multiple rows with same meta_key (if error is related with queries with meta_key, if not - adjust column name)

Add GROUP BY meta_key or LIMIT 1 to your sub-queries. E.g.

How to restore normal JTable row selection?; undo table.setRowSelectionAllowed(false)

Asked 2021-Dec-23 at 08:01

Description

At the beginning selecting a row using mouse click or keyboard arrows is possible with the selected row being colored with the normal row selection color.
User can select single row.
User can lock the selected row using code invoked by lock button. Locking itself is made possible by imitating a selected row (which I'm not sure if it is the proper way of doing so) and is done by two things:
- Color the selected row using DefaultTableCellRenderer
- Disable JTable row selection setRowSelectionAllowed(false)
User can unlock/restore normal selection using code invoked by unlock button. Unlocking is simply to undo the steps of locking:
- Remove coloring of the selected row using DefaultTableCellRenderer
- Enable JTable row selection setRowSelectionAllowed(true) <-- (does not work)

QUESTION

Select some objects from a list of objects based on list of one field

Asked 2021-Sep-05 at 14:33

I have an arraylist of objects which has a field "name" and I have a list of names. I have to select all the objects which consist of any of the name from the list. How can I achieve this in java most efficiently. Any code snippet will be highly appreciated.

Example:

Let the class name be A

A consists of fields such as id, name, subject etc.

So let's assume I have a list
List objectsA
whose length let's say is 10. In this list, the name field consists of various names for eg alpha, beta, gama, delta etc etc.

So suppose I have a second list

If you have a List of names, then it's probably convenient to transform it to a Set so that you can easily check if it contains a name or not:
