Finding a set of values-CodePudding

I have a curve_hex generator, it uses two coordinates, I'm looking for only one coordinate. The script searches for one coordinate value easily, but if I specify several coordinates for the search, then it does not find anything.

wanted='58611774815559422402170859520215717661755632997646071327165159211728464937238'
curve_hex='(58611774815559422402170859520215717661755632997646071327165159211728464937238, 108722706890170119196943746054760504186165603293283329661416022207913727808252)'
if str(curve_hex).find(wanted)!=-1:
   print (curve_hex[str(curve_hex).find(wanted):str(curve_hex).find(wanted) len(wanted)])
else:
    print ('not')

One value is found normally. But if I add several values, the script writes an error

Tell me how to do it right. What am I doing wrong. I have just started learning python.

Very exciting that you are learning python, I would also suggest that you might want to spend some time in the stackoverflow section explaining how to ask a question because I am not 100% sure what you are trying to achieve with your code.

From my understanding, if you are happy with your if else conditions, and your only problem is that you can’t add multiple values to wanted. I would convert wanted to a list that includes all your wanted values, and loop over those.

Something like this:

wanted = ['586..{copy the whole value here}', '108...{copy the value here}']
curve_hex='(58611774815559422402170859520215717661755632997646071327165159211728464937238, 108722706890170119196943746054760504186165603293283329661416022207913727808252)'
for value in wanted:
    if str(curve_hex).find(value)!=-1:
       print (curve_hex[str(curve_hex).find(value):str(curve_hex).find(value) len(value)])
    else:
        print ('not')

Edit: formatting and typos

Made a selection of curves. In this range, these parts of the curves are available. I fixed the script as you suggested. But search stopped working as well as recording. I just want to know how curves work with this script.

import os, binascii, bitcoin
while True:
 hex_key = '00000000000000000000000000000000000000000000000000000000000000'   binascii.b2a_hex(os.urandom(2))
 decoded_key = bitcoin.decode_privkey(hex_key,'hex')
 print (hex_key)
 curve_hex=bitcoin.privkey_to_pubkey(decoded_key)
 wanted = ['90040672269639781867601170828097460642155183514693739441068299505511569496110', '54485907183099442435241830545487744604431707282385107218140713089194934994051']
for value in wanted:
 if str(curve_hex).find(value)!=-1:
  dosya2 = open("br2.txt", "a")
  dosya2.write(hex_key)
  dosya2.close()

You are misleadiong some basic concepts:

Difinitions like this result in diferent types

    wanted='58611774815559422402170859520215717661755632997646071327165159211728464937238'

    type(wanted) # tuple

    curve_hex='(58611774815559422402170859520215717661755632997646071327165159211728464937238, 108722706890170119196943746054760504186165603293283329661416022207913727808252)'
    type(wanted) # string

So you should choose a type first. Tuple is the best case.

    wanted=('58611774815559422402170859520215717661755632997646071327165159211728464937238', '108722706890170119196943746054760504186165603293283329661416022207913727808252')
    curve_hex=('58611774815559422402170859520215717661755632997646071327165159211728464937238', '108722706890170119196943746054760504186165603293283329661416022207913727808252')
    for i in wanted:
        for x,j in enumerate(curve_hex):
            if i in j:
                print(f'{i} in {curve_hex} at position {x}')
