5. What is the polyalphabetic secret word? PYTHON
6. Decrypt this message, which was encrypted using the same secret word:
"EbZhdaV[h^bTpchhQnhig]X[VmhhRP]ftXVnRfjVY]fgtO_X]("
>>> from ciphers.poly import PolyCipher
>>> cipher = PolyCipher('PYTHON')
>>> cipher.decrypt('EbZhdaV[h^bTpchhQnhig]X[VmhhRP]ftXVnRfjVY]fgtO_X](')
