code works in python shell, but not in a terminal

Thank you, I tried that but there was no hidden character.

Turns out, I had missed a bracket in the line 70 print('Resizing the row heights for row %s to max_row...' % (startRow))

I forgot the last bracket. After that, the routine almost worked, except in line 60 I needed to put str(startRow) because startRow is an integer.

Now it works, and I have learned about the power of brackets!!

Thanks for your good advice!
