Why in the Lord's name is sys.stdout None?

i don't know i just use: pip install alive-progress

and try the code in a new .py file

Yeah, he is right! WHY? The imports were just starting to execute, and the default param I've set for _write can't resolve sys.stdout.write?? That doesn't make any sense. Please give me more info:

sorry man i m not a professional coder.. i just installed alive-progress with pip and put the example code in new .py so the code is:

from alive_progress import alive_bar

with alive_bar(1000) as bar: for i in compute(): bar()

python version 3.9 64bit i run that code from IDLE - RUN - RUN MODULE

* What python are you using?

* What is the exact program you tried to run?

* How did you call it?

* Where did you call it, shell or ipython?

Ahhh I see, it's that IDLE thing... It is not a Python environment, it is a program running on top of it... Unfortunately, programs can do whatever they want, and IDLE in particular is known to break stuff.

Anyway, you can run your prog.py directly in the shell:

> python prog.py

And to experiment and explore python, i strongly recommend ipython, it's awesome! Just:

> pip install ipython

And then start it: ipython. In there you can write and test code at the same time, and reuse past inputs and outputs.

OK, I'm closing this one, as it's not a problem.

@rsalmei Offtopic but I'm curious: Have you ever tried https://github.com/bpython/bpython? It looks pretty cool, but I haven't tried it myself

rsalmei commented 3 years ago

Hey @TheTechRobo, YES! It was once my favorite Python REPL, but unfortunately it wasn't working anymore last time I've checked... I don't recall exactly what was the problem, it was long ago, ~3 years, but I had to switch to ipython, and started recommending it instead. But do try it! And let me know if it is working nowadays... 👍

TheTechRobo commented 3 years ago

@rsalmei Seems to work fine for me!

Cool! It is awesome to discover new frameworks, with that auto-docstrings panel! 👍
