Hello,
In Python 3.6.0, % formatting fails to find formatting code after a null byte in bytes type.
Example:
>>> "%s_\x00%s" % ("hello", "world")
'hello_\x00world'
>>> b"%s_\x00%s" % (b"hello", b"world")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: not all arguments converted during bytes formatting
In contrast, the exact same code works as expected in Python 3.5:
>>> "%s_\x00%s" % ("hello", "world")
'hello_\x00world'
>>> b"%s_\x00%s" % (b"hello", b"world")
b'hello_\x00world'
I used Python 3.6.0 that I installed using pyenv 1.0.8 on Kubuntu 16.04 x86_64.

Yes, this is a regression in 3.6.0 and it has been fixed in #29714 for 3.6.1. Try the new version. :-) |

Sorry, the fix is for 3.6.2 so 3.6.1 would still suffer from it. :-( |
