Why Python is a Top Choice for Developers

When we run code in Python, many things happen inside Python.

Let's look at a sample.

print("Hello Chai Sir")

def chai(n):
    print(n)

chai("Chai using python")

Then, if we import it into another file, it looks like this:

from hello_python import chai

chai("Indian Chai")

Something interesting happens: in VS Code, a new folder named “__pycache__” appears.

Now the question is, why is this folder created and who creates it?

When we write code in VS Code and run it, the code is first converted into bytecode and then executed in the Python virtual machine. In most cases, this bytecode is hidden, but in some special cases, it appears in front of the programmer.
