Ignore unconverted data from date-time stamp when using strptime - python-3.5

Question

A third party API returns me a CSV data containing date time stamp like this:
dtval = '2016-10-14 05:09:30+00:00'
I have to convert it in the format : mm/dd/yyyy.
Here I'm not sure about last +XX:XX of directive:
datetime.datetime.strptime(dtval, "%Y-%m-%d %H:%M:%S+XX:XX").strftime('%m/%d/%Y')
I tried followings but did not work:
>>>datetime.datetime.strptime('2016-10-14 05:09:30+00:00', '%Y-%m-%d %H:%M:%S')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/_strptime.py", line 500, in _strptime_datetime
tt, fraction = _strptime(data_string, format)
File "/usr/lib/python3.5/_strptime.py", line 340, in _strptime
data_string[found.end():])
ValueError: unconverted data remains: +00:00
>>>datetime.datetime.strptime('2016-10-14 05:09:30+00:00', "%Y-%m-%d %H:%M:%S%z")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/_strptime.py", line 500, in _strptime_datetime
tt, fraction = _strptime(data_string, format)
File "/usr/lib/python3.5/_strptime.py", line 337, in _strptime
(data_string, format))
ValueError: time data '2016-10-14 05:09:30+00:00' does not match format '%Y-%m-%d %H:%M:%S+%z'
Is there any option in the Python3.4+'s datetime module to ignore remainging unconverted data?
I gone through this but did not find any such option

After a little bit research I found this fix in django's source code :
class FixedOffset(tzinfo):
"""
Fixed offset in minutes east from UTC. Taken from Python's docs.
Kept as close as possible to the reference version. __init__ was changed
to make its arguments optional, according to Python's requirement that
tzinfo subclasses can be instantiated without arguments.
"""
def __init__(self, offset=None, name=None):
if offset is not None:
self.__offset = timedelta(minutes=offset)
if name is not None:
self.__name = name
def utcoffset(self, dt):
return self.__offset
def tzname(self, dt):
return self.__name
def dst(self, dt):
return timedelta(0)
def get_timezone(offset):
"""
Returns a tzinfo instance with a fixed offset from UTC.
"""
if isinstance(offset, timedelta):
offset = offset.seconds // 60
sign = '-' if offset < 0 else '+'
hhmm = '%02d%02d' % divmod(abs(offset), 60)
name = sign + hhmm
return FixedOffset(offset, name)
def custom_strptime(self, value):
"""Parses a string and return a datetime.datetime.
This function supports time zone offsets. When the input contains one,
the output uses a timezone with a fixed offset from UTC.
Raises ValueError if the input is well formatted but not a valid datetime.
Returns None if the input isn't well formatted.

datetime_re = re.compile(
r'(?P<year>\d{4})-(?P<month>\d{1,2})-(?P<day>\d{1,2})'
r'[T ](?P<hour>\d{1,2}):(?P<minute>\d{1,2})'

r'(?P<tzinfo>Z|[+-]\d{2}(?::?\d{2})?)?$'
)
match = datetime_re.match(value)
if match:

if kw['microsecond']:
kw['microsecond'] = kw['microsecond'].ljust(6, '0')
tzinfo = kw.pop('tzinfo')
if tzinfo == 'Z':
tzinfo = utc
elif tzinfo is not None:
offset_mins = int(tzinfo[-2:]) if len(tzinfo) > 3 else 0
