Hello,

When I use Python3 the following cell produce an error :

%%pep8
a=5

TypeError Traceback (most recent call last)
in ()
----> 1 get_ipython().run_cell_magic('pep8', '', 'a=5')

/usr/local/lib/python3.4/dist-packages/IPython/core/interactiveshell.py in run_cell_magic(self, magic_name, line, cell)
2262 magic_arg_s = self.var_expand(line, stack_depth)
2263 with self.builtin_trap:
-> 2264 result = fn(magic_arg_s, cell)
2265 return result
2266

TypeError: 'str' does not support the buffer interface

Thanks for your help.

I'm trying to run pep8_magic in jupyter notebooks, following this example. However, when I have %%pep8 in a cell, I get a Permission error:

INFO:pep8: ...\AppData\Local\Temp\tmp67jjo44b:1:1: E902 PermissionError: [Errno 13] Permission denied: '...\\AppData\\Local\\Temp\\tmp67jjo44b'

I'm currently using Jupyter 4.1.0 and ipython 5.1.0

Trying to get pep8 magic working:
