I would like to get into Machine learning. The problem I have is that my Math

sorted({1: 'D', 2: 'B', 3: 'B', 4: 'E', 5: 'A'}) is equivalent to
sorted(iter({1: 'D', 2: 'B', 3: 'B', 4: 'E', 5: 'A'}))
and iter(dict) iterates over the dict keys, so when you do
iter({1: 'D', 2: 'B', 3: 'B', 4: 'E',
my_dict = {1: 'D', 2: 'B', 3: 'A', 4: 'E', 5: 'B'}

Hi,
I just see the tutorial says Python can return value in function, it does
not say multiple data results return situation. In C, it is possible.
How about Python on a multiple data return requirement?
Thanks,

Hi,
I find the following results are interesting, but I don't know the difference
between list() and list.
>>> nums=list()
>>> nums
[]
>>> xx=list
>>> xx
>>> nums
[]
>>> print(xx)
>>> print(nums)
[]
>>>
Could you tell me that?
Thanks,

'list()' invokes the list class, which creates and returns a new list.
Since you haven't passed any arguments, the lis

The problem here is in the system call contract, which is broken.

More to the point: you don't need classes for objects -- even in t

Technically, neither C nor Python can return mult

Since dictionaries don't actually have any sort of order to them, the
best thing to do is usually to simply display it in order. And there's

I feel slightly cheated.
Folks, I'm not interested in rehashing this. I don't know what all the
open file descriptors are. Some/many/most will have been opened by
underlying C++ libraries and will not have been opened by code at the
Python level. I do think the addition of an os.fsync() attempt on each
file descriptor befo

Using paramiko's exec_command(), i would like to send a command, process its
output and do it for several other commands. I notice that its not quick enough

How would I handle that scenario AND also providing multiple commands together
