In python a tuple consists of a number of values separated by commas.
see: https://docs.python.org/3/tutorial/datastructures.html#tuples-and-sequences
or https://docs.python.org/2/tutorial/datastructures.html#tuples-and-sequences
for Python 2.

The round parentheses aren't significant.

So:

>>> def Executable(arg):
...     return arg
...
 >>> executables = [Executable("salut.py")],
 >>> executables
 (['salut.py'],)
>>>
