Python

I would take any sweeping claims made here with a grain of salt.I've known a number of places that were just python shops. I personally primarily use python, but I work in the data science/ML space where python is sorta the default language.

The nice thing about python is it's easy to jump into (with the REPL and Jupyter Notebooks) and can be used for scripting without needing to learn too much.

The person above is right though that many software development teams will use more structured/rigid languages, but that's going to vary a lot. For instance I've worked at places where the primary language used was Kotlin (Java "compatible"), C#, PHP, or Python. Rust is a big up and coming language, but that depends on the type of software you want to write. And generally once you understand "programming" jumojng between languages isn't as hard.

In summary, my opinion is that python can be a good starter language for self learners as it's more approachable and widely used/popular. However more structured languages can teach you better fundamentals which could carry you further if you're looking to make a career out of programming.
