6Result
7
8t1 = t2 + t3
9
10Sum of t2 and t3. Afterwards t1-t2 == t3 and t1-t3 == t2 are true. (1)
11
12t1 = t2 - t3
13
14Difference of t2 and t3. Afterwards t1 == t2 - t3 and t2 == t1 + t3 are true. (1)(6)
15
16t1 = t2 * i or t1 = i * t2
17
18Delta multiplied by an integer. Afterwards t1 // i == t2 is true, provided i != 0.
19
20In general, t1 * i == t1 * (i-1) + t1 is true. (1)
21
22t1 = t2 * f or t1 = f * t2
23
24Delta multiplied by a float. The result is rounded to the nearest multiple of timedelta.resolution using round-half-to-even.
25
26f = t2 / t3
27
28Division (3) of overall duration t2 by interval unit t3. Returns a float object.
29
30t1 = t2 / f or t1 = t2 / i
31
32Delta divided by a float or an int. The result is rounded to the nearest multiple of timedelta.resolution using round-half-to-even.
33
34t1 = t2 // i or t1 = t2 // t3
35
36The floor is computed and the remainder (if any) is thrown away. In the second case, an integer is returned. (3)
37
38t1 = t2 % t3
39
40The remainder is computed as a timedelta object. (3)
41
42q, r = divmod(t1, t2)
43
44Computes the quotient and the remainder: q = t1 // t2 (3) and r = t1 % t2. q is an integer and r is a timedelta object.
45
46+t1
47
48Returns a timedelta object with the same value. (2)
49
50-t1
51
52equivalent to timedelta(-t1.days, -t1.seconds, -t1.microseconds), and to t1* -1. (1)(4)
53
54abs(t)
55
56equivalent to +t when t.days >= 0, and to -t when t.days < 0. (2)
57
58str(t)
59
60Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t. (5)
61
62repr(t)
63
64Returns a string representation of the timedelta object as a constructor call with canonical attribute values.me.timedelta(days=-1, seconds=68400)
