Is there a way to detect if a block of code in the script itself contains a specific word
... and decide execution of that block based on the presence of that word?
For example I have this:
for frame in range(10):
with open('frame_init.gro', 'w') as g:
# do something
with open('frame_next.gro', 'w') as h:
# do something
When "frame" reaches 9, I don't want the whole with open('frame_next.gro', 'w') as h block to execute at all. Of course I have considered just encasing it in a if frame != 9 but my actual entire code is really long so it would be nice if I could just scan my script within the script itself if it is possible.
For those curious about what other things frame_next.gro is involved in, the answer is lots of calculations

This sounds like an XY problem. Can you explain what problem you are trying to solve with it?

You can do something like this:
a = 0
b = 1
print a + b
with open(__file__, 'r') as f:
lines = f.read().split('n')
val = int(lines[0].split(' = ')[-1])
new_line = 'a = '.format(val+1)
new_file = 'n'.join([new_line] + lines[1:])
with open(__file__, 'w') as f:
f.write('n'.join([new_line] + lines[1:]))
