help(random.seed)
|
|
Help on method seed in module random:
|
|
|
|
seed(a=None, version=2) method of random.Random instance
|
|
Initialize internal state from a seed.
|
|
|
|
The only supported seed types are None, int, float,
|
|
str, bytes, and bytearray.
|
|
|
|
None or no argument seeds from current time or from an operating
|
|
system specific randomness source if available.
|
|
|
|
If *a* is an int, all bits are used.
|
|
|
|
For version 2 (the default), all of the bits are used if *a* is a str,
|
|
bytes, or bytearray. For version 1 (provided for reproducing random
|
|
sequences from older versions of Python), the algorithm for str and
|
|
bytes generates a narrower range of seeds.
