Brute force password breaker

Your belief is correct. Both are lists.
When I try to split liDict get this:

Error:
AttributeError: 'list' object has no attribute 'split'

Suggestion how to do a split is appreciated.

Now I removed unnecessary list:

import PyPDF2

pdfFile = open('reverse.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFile)
pdfWriter = PyPDF2.PdfFileWriter()
for pageNum in range(pdfReader.numPages):
	pdfWriter.addPage(pdfReader.getPage(pageNum))
pdfWriter.encrypt('inside')
resultPdf = open('encryptedreverse.pdf', 'wb')
pdfWriter.write(resultPdf)
resultPdf.close()

helloDict = open('dictionary.txt')
helloDictCont = helloDict.read().splitlines()

PdfFile2 = open('encryptedreverse.pdf', 'rb')
pdfReader2 = PyPDF2.PdfFileReader(PdfFile2)
print(pdfReader2.isEncrypted)

for word in helloDictCont:
	if pdfReader2.decrypt(word) == 1:
		break
		print(word)
	elif pdfReader2.decrypt(word.lower()) == 1:
		break
		print(word)
