Suppose this data set is in a Data Frame named MyStudents. How to fix the missing data for Student ID in the second row?

MyStudents$["$Student ID$"].$fillna$($MyStudents$["$Student ID$"].$mean$(),$ inplace $=$ True$)$

MyStudents.dropna$()$

MyStudents.loc$[1,$"Student ID$"]=$ MyStudents$["$Student ID$"].$mean$()$

MyStudents.drop$($index $=1)$

MyStudents.loc$[2,$"Student ID$"]=$ MyStudents$["$Student ID$"].$median$()$
