extract index of element in list python

I have a list named 'partition'

And i try to extract the index of an element (1 for example) with this code:
a= partition.index(1)
But i get this error :
ValueError Traceback (most recent call last)

----> 1 a= partition.index(1)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
Can you help me please to fix this error?
Kind regards

This should solve the problem:

result = [(i, np.where(j == 1)[0]) for i, j in enumerate(partition) if np.any(np.where(j == 1))]
print(result)
The result will be in the format of (This is an example):
[(*the index of the array*, *an array with all indexes of the elements that are 1*), (*the index of the array*, *an array with all indexes of the elements that are 1*)]
I'm not sure if this is the best way to do it though.
Or if you have a list of numpy arrays you could do something like this:
from numpy import array
partition = [array([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,

Python : Creating raw ECC-ECDSA-SECP256R1 private(32-bytes) and public(64-bytes) keys

I want to generate raw 32-bytes private key and raw 64-bytes public key (ECC-SECP256R1) using Python.
Which library should I install in my Python 3.7 and what APIs do I call to be able to generate raw keys?
Please help.
TIA.

The ECDSA library can do this.
Generate a key pair:
import ecdsa
sk = ecdsa.SigningKey.generate(curve=ecdsa.SECP256k1)
vk = sk.get_verifying_key()
# Your byte values will vary, each time you generate(). Here is an example pair.
skBytes = sk.to_string()
print(f"Signing key = {[b for b in skBytes]}")
# [242, 122, 66, 46, 189, 185, 103, 40, 162, 156, 155, 213, 77, 38, 251, 23, 148, 207, 49, 206, 122, 63, 117, 150, 196, 115, 82, 203, 95, 104, 60, 227]
vkBytes = vk.to_string()
print(f"Verifying key = {[b for b in vkBytes]}")
# [31, 164, 220, 214, 106, 22, 45, 112, 244, 49, 124, 250, 217, 209, 51, 83, 161, 239, 137, 124, 25, 220, 112, 116, 80, 9, 64, 130, 9, 27, 92, 198, 123, 146, 213, 154, 142, 148, 90, 6, 142, 177, 31, 151, 215, 9, 216, 36, 51, 27, 222, 224, 132, 7, 39, 227, 48, 31, 244, 218, 206, 59, 249, 196]
The key pair can be restored from bytes:
skBytes = bytes([242, 122, 66, 46, 189, 185, 103, 40, 162, 156, 155, 213, 77, 38, 251, 23, 148, 207, 49, 206, 122, 63, 117, 150, 196, 115, 82, 203, 95, 104, 60, 227])
vkBytes = bytes([31, 164, 220, 214, 106, 22, 45, 112, 244, 49, 124, 250, 217, 209, 51, 83, 161, 239, 137, 124, 25, 220, 112, 116, 80, 9, 64, 130, 9, 27, 92, 198, 123, 146, 213, 154, 142, 148, 90, 6, 142, 177, 31, 151, 215, 9, 216, 36, 51, 27, 222, 224, 132, 7, 39, 227, 48, 31, 244, 218, 206, 59, 249, 196])
sk = ecdsa.SigningKey.from_string(skBytes, curve=ecdsa.SECP256k1)
vk = ecdsa.VerifyingKey.from_string(vkBytes, curve=ecdsa.SECP256k1)
# or vk = sk.get_verifying_key()

signature = sk.sign(message)
print(f"{[b for b in signature]}")
# [161, 22, 110, 48, 232, 36, 152, 153, 22, 7, 177, 219, 157, 102, 237, 57, 243, 216, 186, 207, 22, 168, 170, 247, 216, 235, 160, 13, 35, 37, 141, 237, 63, 50, 84, 31, 203, 95, 212, 91, 13, 150, 156, 125, 255, 197, 30, 133, 193, 174, 129, 174, 192, 33, 90, 160, 243, 78, 96, 92, 38, 1, 237, 129]

ECDSA Signing and Verifying issue between python ECDSA and C micro-ecc library

python - subtracting ranges from bigger ranges

The problem I have is that I basically would like to find if there are any free subnets between a BGP aggregate-address (ex: 10.76.32.0 255.255.240.0) and all the network commands on the same router (ex: 10.76.32.0 255.255.255.0, 10.76.33.0 255.255.255.0)
In the above example, 10.76.34.0 -> 10.76.47.255 would be free.
I'm thinking of tackling this problem by converting the IP addresses and subnet masks to binary and subtracting that way.
To keep it simple I will keep this example in decimal but doing this would leave me with the following problem: let's say I have a range from 1 to 250, I subtract from this a smaller range that goes from 20 to 23, I would like to end up with a range from 1 to 19 and 24 to 250.
Using the range command doesn't really give me the expected results and while I could possibly create a list with every item in the range and subtract another list with a sub-set of items, it seems to me that it might not be a good idea to have lists with possibly tens of thousands of elements.
Hunor

If you are trying to create a "range" with a gap in it, i.e., with 1-9 and 24-250, you could try to use filterfalse (or ifilterfalse if you are using Python 2.X) from the itertools module, which takes as its arguments a predicate and a sequence, and returns elements of the sequence where the predicate returns False. As an example, if you do:
from itertools import filterfalse
new_range = filterfalse(lambda x: 20 <= x <= 23, range(1,251))
new_range will be an iterable containing the numbers 1-19, and 24-250, which can be used similarly to range():
for i in new_range:
do_things()

The question has been asked long ago but I want to add numpy array answer.

Is there a way to make this sequence creator faster?

I hope someone can give me some tips on how to speed up the following process. Its not really slow, but any time won could be very helpful.

print DELTA_TIME
Time measured is usually around 0.018 sec (on my computer that is).
NeighborsperColumn represents all neighbors that are allowed to be chosen next after a certain column. Their index corresponds to the number from Column_Numbers2 -1.
Now I wonder if there is a possibility to speed this up by doing some things in a different way. The results should be a sequence of all column numbers from Column_Numbers2 (numbers 1 to 266 in this case). This script does work, but I have to do many iterations with it so I'm wondering if there's a way to save some time.
Thanks

Thank you for the working example. This allowed my to help you. Here is some code. The basic idea is to replace:
shuffle(Column_Numbers2)
with
Column_Numbers2 = np.random.permutation(Column_Numbers2).tolist()
This makes your code about 3 times faster:
from datetime import datetime
import numpy as np
from random import shuffle
START_CLOCK = datetime.now()
TotalNumbcol = 266

In general you should use a profiler to find the lines in your code that are too slow.

How to find differences of mat files in Python in human readable format?

.mat files can be loaded into Python with:
import scipy.io
matdata1 = scipy.io.loadmat('file1.mat')
matdata2 = scipy.io.loadmat('file2.mat')
the files can then be piped and save the mat files as text by calling the following Python function:
def mat2txt(matdata):
for k, v in matdata.items(): #Python 3 specific
if isinstance(v,dict):
myprint(v)
else:
print (k,v)
The two .mat files that are being compared are of the same structure and type with different values.
I would like to able to identify the different values in human readable format, and not just their location.
I have tried:
diff matdata1.txt matdata2.txt
diff matdata1.txt matdata2.txt | grep "<" | sed 's/^<//g'
grep -v -F -x -f matdata1.txt matdata2.txt
which do not point to specific differences in values, and they are not within Python. I hoped to store the .mat files as .txt to be able to create a static state to compare the files data at different dates relative to itself and other files, as well as, affording the opportunity to store in git for future comparisons.
A toy example of the resulting data files are:
matdata1.txt
