Pandas Groupby include missing columns [duplicate]

Hello I have a dataset which is shown below. I am running a groupby clause across several variables. I am getting exactly the output that I need with the exception that some combinations are missing due to lack of data.

Example data:

    age   income    education   usage
0   <50   <100K     highschool  10
1   <50   >100K     college     15
2   <50   <100K     highschool  20
3   >50   >100K     college     14
4   >50   >100K     highschool  30

Example code:

grouped_obj = df.groupby(['age', 'income', 'education'])['usage'].mean()

Example output:

age  income  education 
<50  <100K   highschool    15
     >100K   college       15
>50  >100K   college       14
             highschool    30

Desired output:

age  income  education 
<50  <100K   highschool    15
             college       missing
     >100K   college       15
             highschool    missing
>50  >100K   college       14
             highschool    30
     <100K   highschool    missing
             college       missing

My actual problem involves ~2.4 million rows and 31 variables and the missing combinations of variables is random and challenging to identify.

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...
