I am working on the file "02-PythonWhirlwindCheatSheet.ipynb".
The first task is:
In Python 3, you can use the Ellipsis literal ... as a 'nop' placeholder for code:  
def will_do_something():
    ...

Finally a tongue-in-the-cheek application of ellipsis is found here
Can you write Python program for it?
 ... Give me a the Python program you requested?
assistant
#Here is the Python program you requested.

# Portable way to get the You-Know-Which object without naming it
class __:
 def __getitem__(__, _):
  return _
___ = __()[...]

# An Ellipsobinary-to-ASCII convertor
class __:
 def __getitem__(__, _):
  return chr(sum(1<<i if _[-i-1] is ___ else 0 for i in range(len(_))))
_ = __()

# Finally, use the That-Which-Must-Not-Be-Named object
print (
 _[...,_,_,...,_,_,_] +
  _[...,...,_,_,...,_,...] +
   _[...,...,_,...,...,_,_] +
    _[...,...,_,...,...,_,_] +
