How did you use your floppy drives on this machine (Open-Write-Close)?

You might have won the 100m dash, except that we couldn't verify your velocity of locomotion without a... run time check. Badumtish. ChrisA

As I recall, you had to set the starting memory address via the front-panel switches — but the details have long since evaporated from my memory. :-( -- -=- Larry -=-

Hi, I can not write to the file. Can someone help me? Thanks from itertools import product valore = input('Inserisci un valore: ') risultato = product(valore, repeat = 3) with open("file.txt", "w") as result: for i in risultato: print (result,"".join(i))

[CmdTree] sub-command friendly cli library for python : )
by Kidney Win Aug. 30, 2016

Aug. 30, 2016

Hi there, I'm winkidney:), Recently when I work on a cli auto-generating task, I tryed "click" and "argparse" to handle it. But I have to write a library myself to do this job finally. I wish this library helps you ：） Project Github Repo: https://github.com/winkidney/cmdtree Why CmdTree? Alternatives: click library argparse library But when you should choose cmdtree? If you need: + fully sub-command support(not group in click) + Higher-level api support(compare to argparse) + More arg-type support(compare to argparse) + decorators has no side-effect on function call You may be a proper user of CmdTree Best wishes

It directly contradicts "In the face of ambiguity, refuse the temptation to guess." If you don't know what the charset is, don't guess. It'll introduce subtle ambiguities and ugly corner cases and will make the life for the rest of us -- who are trying to get their charsets straight and correct -- a living hell. Having such silly "magic" guessing stuff is actually detrimental to the whole concept of properly identifying and using character sets. Everything about the thought makes me shiver.
