The recursive generator implementation seems cuter (and I guess more
efficient) to me; YMMV:
def flatten(x):
if not isinstance(x,list):
yield x
else:
for elem in x:
for subelem in flatten(elem):
yield subelem
Or if you want to modify the argument list in place, as in Neil's
solution:
def flatten_in_place(x):
x[:] = flatten(x)
