Fairly new at Python. I am trying to find a way to return a transposed copy of a 2 x 2 matrix without using Numpy. I appreciate your patience and willingness to share knowledge. This is how far I have gotten.

What I have tried:

Python

import math 
from math import sqrt
import numbers 

def T(self): 

m = [[m[j][i] for j in range(len(m))] for in in range(len(m[0]))
             print("n\")
             for row in rez:
             print(row)

What's

print("n\")

?
Where did you get the code from? Do you understand it at all?
This

m = [[m[j][i] for j in range(len(m))] for in in range(len(m[0]))

is not properly formed. It is supposed to be a nested list comprehension. The correct form should be:

m = [[m[j][i] for j in range(len(m))] for i in range(len(m[0]))]

Suggest you visit some tutorial sites on learning Python.
