On Python 3:
>>> int('\0')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'decimal' codec can't encode character '\x00' in position 0: invalid decimal Unicode string
>>> int('\01')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '\x01'
>>> int('\x80')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 0: unexpected code byte
>>> int('\xc0')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'utf8' codec can't decode byte 0xc0 in position 0: unexpected end of data
On Python 2, it raises ValueError (except for '\0').

The null byte gives UnicodeEncodeError for other conversions too.
Python 3:
int('\0'), float('\0'), complex('\0')
Python 2:
int(u'\0'), long(u'\0'), float(u'\0'), complex(u'0')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'decimal' codec can't encode character u'\x00' in position 1: invalid decimal Unicode string

Loosely related to issue4221. |

On 3.2 it is fixed (I didn't find the related changeset). Not backported to 2.7. |

The behavior seems acceptable in 2.7 too.
>>> int('\0')
Traceback (most recent call last):
