I am confused as to why my digits are not printing correctly from my Matrix column.

It is missing the trailing digits after the first digit. However, it performs the correct operations. I am not sure as to why the output is like this and have looked over my code a few times. I may not be catching something.

I would like your help in finding my logic error.

class Matrix:
 def __init__(self, Rowsp=[]): 
 """Matrix Constructor"""
 self.Rowsp = Rowsp
 self.Colsp = [[self.Rowsp[j][i] for j in range(len(self.Rowsp))] for i in range(len(self.Rowsp[0]))]

 def copy(self):
 """

 """
 copy = 
 rows = len(self.Rowsp)
 cols = len(self.Rowsp[0])

 for i in range(rows):
 copy.append(list())
 for j in range(cols):
 copy[i].append(self.Rowsp[i][j])

 return Matrix(copy)

Test Case

print("The 2nd row is:", A.getRow(2))
print("The 3rd column is:", A.getCol(3))
print()

A.setRow(2, [40, 50])
A.setCol(2, [30, 4, 1])

print(A)

My result:

The 2nd row is: [40, 50, 60]
The 3rd column is: [3, 6]

ERROR: Incompatible row length
ERROR: Incompatible column length
10 20 30
40 50 60

What I should get:

The 2nd row is: [40, 50, 60]
The 3rd column is: [30, 60]

ERROR: Incompatible row length.
ERROR: Incompatible column space.
10 20 30 
40 50 60
