Also, do y'all call main() in the if block or do you just put the code you want to run in the if block?

It really doesn't. It's a scripting language, functions are there but at it's core it runs a script. The issue is that it was so easy to start with that people started doing everything in it, even though it sucks for anything past complex scripts
It is the excel of databases.
What's the difference between a "scripting" language and a "real" one?
It's a scripting language. What means that the computer runs it line by line, without needing to get the entire project first.
That is not how Python works. There are very few languages that work by executing line-by-line anymore. Unix shell scripts are one of the few holdouts. JavaScript also does it to a certain extent; the browser starts executing line-by-line while a compiler step works in the background. Once the compiler is done, it starts execution of the compiled form right where the line-by-line execution left off. It helps JavaScript be more responsive since it doesn't have to wait for the compiler to finish.
I don't know if this applies to other shells, but bash will not only execute your script line-by-line, it will also read it line-by-line. Which means that you can modify the behavior of a running script by editing lines that have not yet been executed*. It's absolutely bonkers, and I'm sure that it has caused more than one system failure, during upgrades.
* For example, if you run the following script
and then edit the third line before the 5 second sleep has elapsed, then the modified line will be executed.
I have run into the problem of modifying a bash script while it is running.
Python still has the
-ioption, and it still runs the same language as the files interface.The
-ioption is simply interactive mode. All commands still go through a compiler.
