Program beginner.
I want to change pubkey to multiple bitcoin addresses at once.
I know sites that I do one by one, but I can't find them
Trying to modify a program
An error occurs.
Can someone help me?

There are many public key addresses.

import hashlib
import base58



# ECDSA bitcoin Public Key
#pubkey = a
pubkey=['0369ce0e757d759689c9141bc4ee08ed37bb8493b268bd9e9c41eecd81fc9e0e51']
# See 'compressed form' at https://en.bitcoin.it/wiki/Protocol_documentation#Signatures
compress_pubkey = False
 

def hash160(hex_str):
    sha = hashlib.sha256()
    rip = hashlib.new('ripemd160')
    sha.update(hex_str)
    rip.update( sha.digest() )
    print ( "key_hash = \t" + rip.hexdigest() )
    return rip.hexdigest()  # .hexdigest() is hex ASCII


if (compress_pubkey):
    if (ord(bytearray.fromhex(pubkey[-2:])) % 2 == 0):
        pubkey_compressed = '02'
    else:
        pubkey_compressed = '03'
    pubkey_compressed += pubkey[2:66]
    hex_str = bytearray.fromhex(pubkey_compressed)
else:
    hex_str = bytearray.fromhex(pubkey)

# Obtain key:

key_hash = '00' + hash160(hex_str)

# Obtain signature:

sha = hashlib.sha256()
sha.update( bytearray.fromhex(key_hash) )
checksum = sha.digest()
sha = hashlib.sha256()
sha.update(checksum)
checksum = sha.hexdigest()[0:8]

#print ( "checksum = \t" + sha.hexdigest() )
#print ( "key_hash + checksum = \t" + key_hash + ' ' + checksum )
print ( "bitcoin address = \t" + (base58.b58encode( bytes(bytearray.fromhex(key_hash + checksum)) )).decode('utf-8'))

I wish good things have been done.
I've had the same thing.

Hi friends Nova Exchange is currently prohibited from depositing money and can not withdraw money at will.
If all coins compare, you will see that the whole transaction is very cheap.
Nova Exchange is expected to close its stores in March 2018.

I think this.
All users will wait a bit if there is a problem with the coin.
But was the question too difficult?
Or was it not worth the answer?
In the past six months I have collected one billion cv2, but sold it today.
I do not know why colx rich list is now
Before describing the problem with the coin
What the rich list coin is
If you do not answer, maybe 1 Satoshi
People will not buy.

=====================
I do not think so. I think it should be less than the actual number of exchanges even if it is common wallet.
I have 200 million colx, but I do not see it when I look up my wallet address.
What is your wallet? It should be seen that coins have been issued.
I think this is what the other person thinks, and colx executives should give quick action and explanation and there will be no price drop.


If you have a common wallet of 12 billion, I do not think you should get your wallet.
People who do not know pos like me can misunderstand without understanding


And I think it 's too long to exchange coins for three months.
And to prevent price declines, I think we should take steps to make sure that colx is traded in a market that trades cv2 as quickly as possible.

http://A huge mistake

I have a question.
Nova change total cv2 ===> 3.2 billion
The colx rich list has a huge colx count.
Is it just a mistake or a scam?

The total number of 1 ~ 4 is more than 10 billion
The reason why colx prices are falling is obvious
People who have seen this will be feeling a shock.
