I have some lines in a text file as
159 J=1661,3169,1679,3181 SEC=SLAB2
66 J=5597,5596,7523,7522 SEC=WALL1
How can I delete "SEC=SLAB2" or "SEC=WALL1" and modify the roginal lines into new ones, if I have RE functions
I am using and stuyding Python. Please forget me to ask some simple questions here. Thank you so much.
