An inexact clone of GNU shuf. Free, implemented in Python.
Same as shuf, but the script is invoked with pyshuf. Read the GNU manual for shuf for more details. I haven't used shuf -- I wrote this because it didn't come standard on MacOS.
Generate a random number from 0 to 99
$ pyshuf -i 0-99 -n 1
73
Pick a random word from the dictionary (dictionary location may vary)
$ pyshuf --input-file /usr/share/dict/words -n 1
irreflectiveness
Shuffle the first 10 words from the dictionary
$ head /usr/share/dict/words | pyshuf
