I have a 2D Numpy array called arr. What is the Python code to: transpose the array; subtract 125 from the first column of all rows; transpose the array again (putting it back in its original state, making sure that all the changes are saved as arr)? I tried this, but it did not work correctly:

arr[:,0]-=125

arr.T

arr>>
