You can only find it if someone has used it on the blockchain, and spent those satoshis. Or you generate it completely randomly yourself(good luck)
Please see the bellow python script:
import time
import requests
addresses = open('addr.txt', 'r').read().split('\n')
for address in addresses:
if address == '':
continue
response = requests.get('
https://blockchain.info/q/pubkeyaddr/' + address)
if response.status_code == 200:
if response.text != '':
open('pubkeys.txt', 'a').write(address + ' : ' + response.text+"\n")
Good Luck & hope you will enjoy it smoothly........
