If the method does a long thing, the keep it long. I do a lot of data analysis and simulation, and so often people who came before had this urge to shorten methods, so we get:
def do_calculation(N, X, y, z, a, b, c):
# Setup stuff
for i in range(N):
calclation(X[i], y, z, a, b, c)`
Sometimes there’s a place for that, like if calculation could be swapped for a different function, or if calculation is used all over the program. It’s a pretty good clue that something is up though when the signatures are almost identical. Of course, that has just led to people writing:

I don’t have issue with methods being 200 lines, as long as they have a singel concept and is easy to follow.
There are various exceptions where up to 200 lines is still okay, yes. The 50 lines rule is more a good rule of thumb.
