sagemath 9.6 beta1 jupyter notebook missing output

[ph h]

Greetings,

Please find attached a screen shot of sagemath 9.6 beta1 jupyter notebook (on Windows Server 2019 WSL Ubuntu, from Sage Introductory Programming Tutorial - Lists, Loops and Set Builders)

1. In [3] only gives A^4 in Out [3] (missing A^0, A^1, A^2 and A^3)
   
2.  In [4] gives no output (but In [8] does)
   
3. In [6] gives no output (but In [7] does)
   

$ uname -a
Linux HPC1 4.4.0-17763-Microsoft #2268-Microsoft Thu Oct 07 16:36:00 PST 2021 x86_64 x86_64 x86_64 GNU/Linux

Thank you for your advice.

Regards,

phiho

There is no bug in all this. To display some item at each step of a loop use show() or print(), e.g.

for i in [0, 1, 2, 3, 4]:
     show(A^i)

Hi,

Sage behavior seems to be different on the console:

A clarification is much appreciated if the 'sage help' is applicable to sage console only:

http://localhost:8888/kernelspecs/sagemath/doc/prep/Programming.html#lists-loops-and-set-builders

Do we have different documentation for the sage console and Jupyter notebook?
