kandi X-RAY | markransom Summary
Markransom is a tool created to encrypt all the files that matches an extension pattern. Can be decrypted with decipher.py and the encryption key generated. The app will generate an AES256 key and an optional messsage in the desktop. You can configure your own settings in the firsts lines of the script. This app was written in 2017.

QUESTION
What is the time complexity of checking membership in dict.items()?
According to the documentation:
Keys views are set-like since their entries are unique and hashable. If all values are hashable, so that (key, value) pairs are unique and hashable, then the items view is also set-like. (Values views are not treated as set-like since the entries are generally not unique.) For set-like views, all of the operations defined for the abstract base class collections.abc.Set are available (for example, ==, <, or ^).
So I did some testing with the following code:

is an O(1) operation (though one with an arbitrarily large constant, related to the complexity of comparing values.)
dictitems_contains
doesn't simply try to hash the tuple and look it up in a set-like collection of key/value pairs.

QUESTION
I found how to compare floats with equality here:
Compare `float` and `float64` in python
Working with floating point NumPy arrays for comparison and related operations
and in other similar questions.
But I can't find the best way how to compare correctly floats with threshold(greater or less).
Example: We want to check if elements in float matrix is less than float threshold.
...ANSWER
Answered 2017-Mar-11 at 17:17In most practical circumstances an exact comparison will be not be possible because of the little errors you collect while doing calculations.
If you want to do proper numerics you'll have to carry an error estimate along with all your results which is quite tedious.
(There is a library called flint with a python interface but I haven't used it so cannot vouch for it. It is designed to do the carrying error bounds (more rigorous than estimates) along all results for you.)
In any case you will have to change the list of possible outcomes from greater, equal, less to something more like greater, probably greater, indistinguishable, probably less, less
