Match the string data inside a group - Pandas

I have dataframe like this:

+--------+------------+----------+--------------+--------------+----------------+--------------+--------------+
| company|          id|ann_rtn_dt|share_class_nb|shrhldr_seq_nb|shrhldr_first_nm|shrhldr_mid_nm|shrhldr_sur_nm|
+--------+------------+----------+--------------+--------------+----------------+--------------+--------------+
|SYNTHE01|SYNTHE01_1_1|2022-11-28|             1|             1|            NIEL|        ANDREW|        HOPSON|
|SYNTHE01|SYNTHE01_3_1|2022-11-28|             3|             1|          NICOLE|        CLAIRE|          MORE|
|SYNTHE01|SYNTHE01_1_2|2022-11-28|             1|             2|               N|             C|          MORE|
|SYNTHE01|SYNTHE01_2_1|2022-11-28|             2|             1|            NEIL|        ANDREW|        HOPSON|
|SYNTHE01|SYNTHE01_3_1|2022-11-28|             3|             1|          NICOLE|        CLAIRE|          MORE|
|SYNTHE02|SYNTHE02_1_1|2022-11-28|             1|             1|            MIKE|              |        LOPSON|
|SYNTHE02|SYNTHE02_3_1|2022-11-28|             3|             1|          NIMIKE|              |        LOPSON|
|SYNTHE02|SYNTHE02_1_2|2022-11-28|             1|             2|            MIKE|              |        LOPSON|
|SYNTHE02|SYNTHE02_2_1|2022-11-28|             2|             1|            MIKE|              |        LOPSON|
+--------+------------+----------+--------------+--------------+----------------+--------------+--------------+

The whole dataframe can be grouped 2 distinct company column i.e. SYNTE01 and SYNTHE02.

My use case is to do matching inside the company.

STATUS_1 is set to min of id, when there is full match of shrhldr_first_nm, shrhldr_mid_nm and shrhldr_sur_nm in the grouop.

STATUS_2 is set to min of id, when there is match of first byte of shrhldr_first_nm and shrhldr_mid_nm in the group. And shrhldr_sur_nm matches exactly.

For eg. in COMPANY SYNTHE01, NIEL ANDREW HOPSON in row1 matches with NIEL ANDREW HOPSON in row4. The column STATUS_1 is set to min of id column for both.

For eg. in COMPANY SYNTHE01, the first byte of NICOLE CLAIRE MORE in row2 matches with N C More in row3. The column STATUS_2 is set to min of id column for both.

My output dataframe would look like below:

+--------+------------+----------+--------------+--------------+----------------+--------------+--------------+-------------+-------------+
| company|          id|ann_rtn_dt|share_class_nb|shrhldr_seq_nb|shrhldr_first_nm|shrhldr_mid_nm|shrhldr_sur_nm|     STATUS_1|     STATUS_2|

We tried this in Pyspark, could not achieve it. We are now trying to do it in Pandas. Please suggest any possible approach. Thank you.

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...
