I can't enter any input

Description

What steps will reproduce the problem?

All the programs I’m trying to run having inputs produce me the same errors over and over again.

I looked for the solution in internet and got to run:

conda create -n spyder-cf -c conda-forge spyder conda activate spyder-cf spyder

In my still little programming knowlegde I think that’s leading me to create a new enviroment, where I can run the inputs, but I’d prefer not to have to create a enviroment everytime I close it, or, better, to understand why this is happening and learn to fix it.

How can I solve this problem and what is happening?

Thanks in advance 😃

Great! That’s an amazing answer 😃

Thanks so much. I’m just starting in Spyder, and don’t know much about programming yet, so it’s really good to get to know how things work.

Glad to hear that you got Spyder setup! Regarding your questions:

This launcher, Spyder (spyder-cf), didn’t exist in my computer before?

Exactly, it was created when you created the new spyder-cf and Spyder got installed there.

Is it an independent part of Spyder that I created with an specific version?

When you install Spyder in an environment it will create a shortcut (at least on Windows) which will launch it taking care of activating the correct environment where Spyder was installed. So basically that shortcut will launch the Spyder version that is installed in your spyder-cf environment. If for example in the future you update Spyder to a newer release on the spyder-cf environment the same shortcut will allow you to launch the newer Spyder version.

If that’s the case, should I guess I can create as many enviroments as I please in my PC to work simultaneously with all of them?

For each environment where you install Spyder you will get a unique shortcut to launch Spyder from a specific env. So for example, if you want to install different Spyder installations you could create multiples environments each one with a different Spyder version and then you will have a shortcut for each of them. However, take into account that the folder for the Spyder configs and preferences is the same for all the Spyder versions you launch, which then could cause troubles if the config has been changed between versions. For that way of working though, Spyder has some command line flags like --conf-dir that you can use to choose an specific directory that Spyder should use to save and load its configuration files. Also, you can connect Python interpreters from different environments using the Spyder preferences. For more info about the way to work with Spyder and multiple environments you can check the Spyder docs FAQ page: https://docs.spyder-ide.org/current/faq.html#using-spyder
