How to iterate through maildir messages in python 3?

In python 2 one can do:- for msg in maildir: print msg # or whatever you want to do with the message However in python 3 this produces "TypeError: string argument expected, got 'bytes'". How should one iterate over a maildir in python3? (I've been here before but this probl

round decimal values

Hi, this code generate 4 values with gaussian distribution (mu=5, sigma=1): import numpy as np x = np.random.normal(5, 1, 4) print(x) Output: [5.87879753 3.29162433 3.83024698 4.92997148] I would like to round the output like this: [6, 3, 4, 5] What should I add to the code? Thank you j.

RE: Optimizing Small Python Code

Barry, I am not going to continue replying in this thread. I made my point and it was focused after a while on the size of the CODE. Of course, the code can be made ever smaller using gimmicks and yet run longer or use more memory or CPU. If you have control of a package with a short name l

You're right, I was making an academic point. I think this whole compression question relates to Kolmogorov complexity "In algorithmic information theory (a subfield of computer science and mathematics), the Kolmogorov complexity of an object,

RE: Optimizing Small Python Code

Jan, As an academic discussion, yes, many enhancements only pay off when things are larger. And for most purposes, I/O is so much slower that it makes little difference. But on a multi-processing machine, extra CPU may impact how much else the machine can do at the same time. Here is an exam

Re: Optimizing Small Python Code

If I'm not mistaken, the original output is O(n^2) in quantity of chars, and as output time is proportional to the length of the output, that makes the output time also O(n^2) here too. So I guess this only looks like it's reduced to linear because the output here is very small. For large n it wou
