Hi,
1) P_og declaration in line 9 can remain the same as list declaration is same in python too
2) You can replace length() with len()
3) Syntax of if and else is little different in python, you can checkout the below resource for that
4) you need to use pow() function in python instead of '^'
5) list accessing in python is done using [] instead of () so you need to replace T(..) to T[] and remember that in matlab indexing starts from 1 unlike python whose list indexing starts from 0
6) You can follow the below cheatsheet to find matlab equivalent functions of python and replace them all
7) You can check out the below resources for sort function in python
Hope it helps,
Thanks
