[Rick J. Pelleg]

New submission from Rick J. Pelleg :

On Windows 10 Education, ran:
ipython
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)]
Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.

After "from turtle import *" and several simple turtle commands:

In [36]: fill()

> 1 fill()

NameError: name 'fill' is not defined

Mmm... right now I cannot reproduce at all, both in iPython and in python.
Will continue to try.

Sorry, all reproduction attempts failed, both in plain Python and in
iPython.
I guess you can close this for now.

Just one more issue: since it happened before I found out that the "turtle"
package already has the pre-defined short version of commands, such as
"fd()", "lt()", etc., the crashed session included four function
definitions, for "fd()", "bk()", "lt()" and "rt()", in the form of:

def fd(val):

forward(val)
