python replace env params in a string which is not a path

Patterns I can receive can vary and I have used

line1 = "$ABC/xyz"
line2 = "123_$ABC_xyz"
line3 = "abc_$XYZ_123_def_$ABC"
line4 = "$XYZ_def_abc"
exp = os.path.expandvars(line)

As I understand expandvars works on line1 and not line2 /line3 So I extracted the pattern with regex --> r"\$([A-Z0-9_]*(?<!_))"

result = re.search(r"(\$([A-Z0-9_]*(?<!_)))", line2)
print (result.group(2))

Problem : How do I pass the variable to os.environ(), as this doesn't seem to accept any variables only strings. I tried even envsubst which also is not working.

And for line3, there are more than one env param i want to replace. Is there any python package which will do the replacement which i can use or do I need to use a recursive call to a function I write?

Any inputs for this would be of great help. Please do let me know if I need to provide any more details.

Expected Ouput: os.environ['ABC'] = 'WSS' os.environ['XYZ'] = 'OK'

line1 = "WSS/xyz"
line2 = "123_WSS_xyz"
line3 = "abc_OK_123_def_WSS"
line4 = "OK_def_abc"

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". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
