In the search  and sort section in the python programming bootcamp I dont understand the insertion sort. 
Below is the code. The part where I put astericks are the parts I dont understand 

Start your code here
Def insertion_sort(my_list)
    n = len(my_list)
    For I in range(1,n)
    Value = my_list[1]
*** J = 1
    While j > 0 and my_list[j-1] > value
          My_list[j] = my_list[j-1]
          J = j -1
          My_list[j] = value  ********
     Return my_list 

When the instructor was testing his code he used the bubble sort function instead of the insertion sort function. Is that meant to be so?.
 
Thank you
