Check whether pattern is in csv field and output into a different file (whole row containing said pattern)

I want to search through a csv file, a particular column (code) for specific pattern(s).

For example

Sample File

I would like to use python to extract rows 1 and 2 given they have the pattern '[0-9][0-9][A-Z]' in the column code

but the last row does not adhere to the above so I would like to negate it and output it into a different csv; and output the criteria that is satisfied onto a new csv.

Other patterns need to be included as well and may be present within the data so this is why I wanted to add it to a list variable and check the pattern that way. For instance a code critera could be '[0-9][0-9][A-Z] [0-9][0-9][A-Z]'. Wonder if it would be best to go with perhaps regex however with a list I feel if there are additional patterns to include or required this can then be added to said list?

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE".
