[New-bugs-announce] [issue5236] time.strptime should reject bytes arguments on Py3

[Ezio Melotti]

New submission from Ezio Melotti <ezio.melotti at gmail.com>:

On Python3 time.strptime(string[, format]) accepts bytes as arguments
and then fails:

>>> strptime(b"2009", "%Y")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Programs\Python30\lib\_strptime.py", line 454, in _strptime_time
    return _strptime(data_string, format)[0]
  File "C:\Programs\Python30\lib\_strptime.py", line 322, in _strptime
    found = format_regex.match(data_string)
TypeError: can't use a string pattern on a bytes-like object

time.strftime already rejects bytes arguments:
>>> strftime(b'%Y')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: strftime() argument 1 must be str, not bytes

time.strptime should do the same and reject bytes for both the arguments
(string and format).

(With Py2.x both str and unicode args work.)
