What does ‘wb’ mean in this code, using Python?

by

File mode, write and binary. Since you are writing a .jpg file, it looks fine.

But if you supposed to read that jpg file you need to use 'rb'

More info

On Windows, ‘b’ appended to the mode
opens the file in binary mode, so
there are also modes like ‘rb’, ‘wb’,
and ‘r+b’. Python on Windows makes a
distinction between text and binary
files; the end-of-line characters in
text files are automatically altered
slightly when data is read or written.
This behind-the-scenes modification to
file data is fine for ASCII text
files, but it’ll corrupt binary data
like that in JPEG or EXE files.
