unsupported operand type(s) for %: 'datetime.timedelta' and 'int'

Question

My python code is as below:

if ( delta % 24 == 0):
    print "ONE DAY "

It gives error as TypeError: unsupported operand type(s) for %: 'datetime.timedelta' and 'int'

delta is of type datetime.timedelta

Please share your inputs to fix this error. Using pyton 2.7 due to project requirement

Answer 1

DateTime doesn't support modulo, thus the error you see.

This Python modulo support for datetime exists though.

---

Moreover, you could cast the second operand, so that the error goes away:

if ( ( d % timedelta(minutes = 24) ) == 0):
     print("ONE DAY")

which works in Python 3.6.1.

EDIT:

This won't work for Python 2.7.0, which was edited to OP's question. In that case, this may help: Manipulating DateTime and TimeDelta objects in python .

Answer 2

What about reading the doc for datetime.timedelta ? Or even just test it in your python shell :

>>> d = datetime.timedelta(hours=24)
>>> d
datetime.timedelta(1)
>>> dir(d)
['__abs__', '__add__', '__class__', '__delattr__', '__div__', '__doc__', '__eq__', '__floordiv__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__le__', '__lt__', '__mul__', '__ne__', '__neg__', '__new__', '__nonzero__', '__pos__', '__radd__', '__rdiv__', '__reduce__', '__reduce_ex__', '__repr__', '__rfloordiv__', '__rmul__', '__rsub__', '__setattr__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', 'days', 'max', 'microseconds', 'min', 'resolution', 'seconds', 'total_seconds']
>>> d.days
1
>>> d = datetime.timedelta(hours=8)
>>> d.days
0

As you can see, you already have the information at hand.

Note that if you need other computations based on hours (not days), you'll need to use delta.seconds / (60 * 60) - for some reasons I can't understand no one ever took care of adding an hours or minutes attributes to timedelta ...
