int as argument does not work.
Fails concatenating the final command string arg_string = " ".join([u(x) for x in args])

s.history('user_name', 10)

Fixed

[ZeroDivisionError]

Still broken for python 3. Because python-utils/luckydonaldUtils/encoding.py does not include commit with this bugfix.

Please update luckydonald-utils to v0.017 or newer.
v0.017 Package is called 0.17 in pip.

I assume this as fixed and working.
