Try

python -c '
import os
for root, dirs, files in os.walk("."):
  if "file.txt" in files:
    dirs[:]=[]
    print(os.path.join(root, "file.txt"))'

(note that it doesn't check that "file.txt" is a *regular* file,
only that it's not a directory (it may still be a symlink to a
directory); while that could be added, I don't expect you would
care much about it).
