Python Dates and Times in Python (2014) Dates and Times Time Tango

Function returns a combined datetime object, but I'm still getting the wrong answer.

This is the way I did it, unless maybe there's an alternate method using operators? Or maybe the solution is looking for something else? I even ran an isinstance test on combined_date and datetime came back true. Not really sure what else to do here.

combo.py
from datetime import datetime


def time_tango(user_date, user_time):
    combined_date = datetime.combine(user_date, user_time)

    return combined_date

Devs: this code should pass. The level of import should not matter in this case. Please review checker behavior.

You got two errors. Let us analyze.

from datetime import datetime πŸ‘ˆ# what is the first datetime? you only need import datetime


def time_tango(user_date, user_time):
    combined_date = datetime.combine(user_date, user_time)πŸ‘ˆ# datetime.combine is a wrong package

    return combined_date

datetime.combine() is a wrong pacakage or datetime don't have the extension of combine(), check it yourself.

try this in the REPL;

>>> import datetime

>>> dir(datetime)
['MAXYEAR', 'MINYEAR', '__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__'
, 'date', 'datetime', 'datetime_CAPI', 'sys', 'time', 'timedelta', 'timezone', 'tzinfo']  
>>> 
>>> dir(datetime.datetime)
['__add__', '__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', 
'__init__', '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', '__radd__', '__reduce__', '__reduce_ex__', '__repr__', '__rsub__
', '__setattr__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', 'astimezone',πŸ‘‰  'combine' πŸ‘ˆ, 'ctime', 'date', 'day', 'dst', 'fold', 
'fromisocalendar', 'fromisoformat', 'fromordinal', 'fromtimestamp', 'hour', 'isocalendar', 'isoformat', 'isoweekday', 'max', 'microsecond'
, 'min', 'minute', 'month', 'now', 'replace', 'resolution', 'second', 'strftime', 'strptime', 'time', 'timestamp', 'timetuple', 'timetz', 
'today', 'toordinal', 'tzinfo', 'tzname', 'utcfromtimestamp', 'utcnow', 'utcoffset', 'utctimetuple', 'weekday', 'year'] 
>>>

As shown, there is no combine() extension with datetime, it should be datetime.datetime.combine().

I think there’s more going on here. All of these should work equally as well:

# as module import
>>> import datetime
>>> help(datetime.datetime.combine)
Help on built-in function combine:

combine(...)
    date, time -> datetime with same date and time fields

# as renamed class import
>>> from datetime import datetime as dt
>>> help(dt.combine)
Help on built-in function combine:

combine(...)
    date, time -> datetime with same date and time fields

# as direct class import
>>> from datetime import datetime
>>> help(datetime.combine)
Help on built-in function combine:

combine(...)
    date, time -> datetime with same date and time fields

This needs further review.

Using the REPL example:

Sweet, thanks. I'm using my own IDE and the command prompt and have different imports for both, so it was probably getting confused.
