使用您的示例，我得到了Python和Java的相同输出。
Java：

import java.math.BigInteger;
import java.security.Key;

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

public class Blowfish1 {

    public static void main(String[] args) throws Exception {
        String s = "testings";
        Cipher cipher = Cipher.getInstance("Blowfish/ECB/PKCS5Padding");
        Key key = new SecretKeySpec("6#26FRL$ZWD".getBytes(), "Blowfish");
        cipher.init(Cipher.ENCRYPT_MODE, key);
        byte[] enc_bytes = cipher.doFinal(s.getBytes());
        System.out.printf("%x%n", new BigInteger(1, enc_bytes));
    }

}

Python：

from Crypto.Cipher import Blowfish
import binascii

# See @falsetru answer for the following method
#
def PKCS5Padding(string):
    byteNum = len(string)
    packingLength = 8 - byteNum % 8
    appendage = chr(packingLength) * packingLength
    return string + appendage

def PandoraEncrypt(string):
    key = b'6#26FRL$ZWD'
    c1  = Blowfish.new(key, Blowfish.MODE_ECB)
    packedString = PKCS5Padding(string)
    return c1.encrypt(packedString)

if __name__ == '__main__':
    s = 'testings'
    c = PandoraEncrypt(s)
    print(binascii.hexlify(c))

在这两种情况下，输出都是223950ff19fbea872fce0ee543692ba7

def PKCS5Padding(string):
    byteNum = len(string)
    packingLength = 8 - byteNum % 8
    appendage = chr(packingLength) * packingLength
    return string + appendage

使用chr代替str。

>>> chr(1)
'\x01'
>>> str(1)
'1'

str * int -> repeated string

>>> '!' * 5
'!!!!!'

对于python 3 https://pycryptodome.readthedocs.io/en/latest/index.html `

    decrypted = c1.decrypt(string)
    last_byte = decrypted[-1]
    decrypted_without_padding = decrypted[:-last_byte]
    return decrypted_without_padding
