Firstly, please answer in layman's terms. I have looked at what feels like hundreds of articles and I have no idea what people are talking about (what is zsh, bash, PATH, all this terminology). All I want is to use Python and install packages so I can use Google Cloud SDK (I am familiar with BigQuery in the UI). I'm so confused by all this Python set up!
Yesterday I successfully downloaded Python, and even managed to somehow install Google Cloud SDK using a few Youtube Tutorials and started using it with BigQuery. Now I don't know what I pressed, but today I open Terminal and none of my code runs! I see this error message: /Users/username/.zshrc:7: command not found: “alias
Even a simple 'cwd' doesn't work... zsh: command not found: cwd
Can someone please help and explain what exactly I'm supposed to be doing? Imagine you're explaining it to your grandma please thanks.
