Example 2: python standard library

>>> from datetime import timedelta
>>> delta = timedelta(
...     days=50,
...     seconds=27,
...     microseconds=10,
...     milliseconds=29000,
...     minutes=5,
...     hours=8,
...     weeks=2
... )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)

Example 3: python standard library

>>> timedelta(hours=-5)
datetiSupported operations:

Operation

Result

t1 = t2 + t3

Sum of t2 and t3. Afterwards t1-t2 == t3 and t1-t3 == t2 are true. (1)

t1 = t2 - t3

Difference of t2 and t3. Afterwards t1 == t2 - t3 and t2 == t1 + t3 are true. (1)(6)

t1 = t2 * i or t1 = i * t2

Delta multiplied by an integer. Afterwards t1 // i == t2 is true, provided i != 0.

In general, t1 * i == t1 * (i-1) + t1 is true. (1)

t1 = t2 * f or t1 = f * t2

Delta multiplied by a float. The result is rounded to the nearest multiple of timedelta.resolution using round-half-to-even.

f = t2 / t3

Division (3) of overall duration t2 by interval unit t3. Returns a float object.

t1 = t2 / f or t1 = t2 / i

Delta divided by a float or an int. The result is rounded to the nearest multiple of timedelta.resolution using round-half-to-even.

t1 = t2 // i or t1 = t2 // t3

The floor is computed and the remainder (if any) is thrown away. In the second case, an integer is returned. (3)

t1 = t2 % t3

The remainder is computed as a timedelta object. (3)

q, r = divmod(t1, t2)

Computes the quotient and the remainder: q = t1 // t2 (3) and r = t1 % t2. q is an integer and r is a timedelta object.

+t1

Returns a timedelta object with the same value. (2)

-t1

equivalent to timedelta(-t1.days, -t1.seconds, -t1.microseconds), and to t1* -1. (1)(4)

abs(t)

equivalent to +t when t.days >= 0, and to -t when t.days < 0. (2)

str(t)

Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t. (5)

repr(t)

Returns a string representation of the timedelta object as a constructor call with canonical attribute values.me.timedelta(days=-1, seconds=68400)
>>> print(_)
