Selecting the folder for performing specific operation on JPG files in tkinter

I have written a function for tkinter GUI in python as below:

def mgpd():
answer = filedialog.askdirectory(parent=root,
initialdir=os.getcwd(),
title="Please select a folder:")
if len(answer) > 2:
with open("output.pdf", "wb") as f:
f.write(img2pdf.convert([i for i in os.listdir(answer) if i.endswith(".jpg")]))
else:
pass
t2.delete(0, 'end')
t2.insert('insert', 'task completed.')


Now when I select a folder the type error is given as TypeError: a bytes-like object is required, not 'str'. The problem is around endswith I guess.

TypeError: a bytes-like object is required, not 'str'

endswith

Python complaining about bytes-like objects is usually because whatever string you're trying to alter is encoded. Instead of if i.endswith(".jpg")], try if i.decode().endswith(".jpg")].

if i.endswith(".jpg")]

if i.decode().endswith(".jpg")]

AttributeError: 'str' object has no attribute 'decode'

i.endswith(b'.jpg')

from binascii import dehexlify

unhexlify(i).endswith(".jpg")]

Finally this is the answer:

def mgpd():
image_files =
answer = filedialog.askdirectory(parent=root,
initialdir=os.getcwd(),
title="Please select a folder:")
if len(answer) > 2:
for file in os.listdir(answer):
if file.endswith(".jpg"):
image_files.append(os.path.join(answer, file))
else:
pass

outfile = os.path.join(answer, 'output.pdf')
pdf_bytes = img2pdf.convert(image_files)
file = open(outfile, "wb")
file.write(pdf_bytes)

t2.delete(0, 'end')
t2.insert('insert', 'task completed.')
