I recently faced a similar issue doing something like this:
data_out = []
for i in range(len(data_in)):
data_out.append([])
This caused me to wonder why Python does not have a "foreach" statement (and
also why has it not come up in this thread)? I realize the topic has probably
been beaten to death in earlier thread(s), but does anyone have the short
answer?
