pybitmessage.helper_random module

Convenience functions for random operations. Not suitable for security / cryptography operations.

seed()[source]

Initialize random number generator

randomBytes(n)[source]

Method randomBytes.

randomshuffle(population)[source]

Method randomShuffle.

shuffle the sequence x in place. shuffles the elements in list in place, so they are in a random order. As Shuffle will alter data in-place, so its input must be a mutable sequence. In contrast, sample produces a new list and its input can be much more varied (tuple, string, xrange, bytearray, set, etc)

randomsample(population, k)[source]

Method randomSample.

return a k length list of unique elements chosen from the population sequence. Used for random sampling without replacement, its called partial shuffle.

randomrandrange(x, y=None)[source]

Method randomRandrange.

return a randomly selected element from range(start, stop). This is equivalent to choice(range(start, stop)), but doesnt actually build a range object.

randomchoice(population)[source]

Method randomchoice.

Return a random element from the non-empty sequence seq. If seq is empty, raises IndexError.
