So your basic shell is working good!
And if you raise error by typing raise and the error the program
will get it and print it as raise command would do!
to make it even better, you can do:
import sys
print("ERROR:", e, file=sys.stderr)

the full form of stderr is standard error and in
some editors and shells it would write text in red color!

But there is a problem: in an actual python shell, when I type something and then use the left and right arrow keys, the cursor will move; however in your shell, when I use arrow keys, say rightarrow, I get ^[[C instead. Is there a way to solve this?

What Linux distro are you using? I'm getting bored of Ubuntu and Pop OS.

[aadityanagarajan]

This is awesome.
I want to make an improvement in it: how to write if, else statements and for and while loop.
Can anyone help me to do this.
