Hi,
I have a Python program that uses Tkinter for its GUI. It's rather slow so I
hope to replace many or all of the non-GUI parts by Julia code. Has anybody
experience with this? Any packages you can recommend? I found three
alternatives:

I have Python 3.9 installed in Windows 10 on my Laptop and have installed
pipenv v-2021.11.5. When I invoke the python shell command, it fails with
thee following errors:
C:\Users\SPM\Apps\Spyder-5.2.1>pipenv shell
Traceback (most recent call last):
File "C:\Python39\lib\runpy.py", line
Additionally I'd like to ask, if you e.g. used pandas and numpy before
you make the effort of rewriting everything.
Yes python is slower than compiled languages, but especially with numpy
you can make use of compiled code underneath.
Of course this could mean rewriting some existing code but stay
Python 3.9.9
Hello
I have some troubles with groupby from itertools
from itertools import groupby
for k, grp in groupby("aahfffddnnb"):
print(k, list(grp))
print(k, list(grp))
a ['a', 'a']
a []
h ['h']
h []
f ['f', 'f', 'f']
f []
d ['d', 'd']
d []
s ['s', 's', 's', 's']
s []
n ['n
but:
li = [grp for k, grp in groupby("aahfffddnnb")]
list(li[0])
[]
list(li[1])
[]
It seems empty ... I don't understand why, this is
the first read of an iterator, it should provide its
data.
The group-iterators are connected. Each group-iterator is a wrapper
around the original it
