Hello Max,
First of all you are doing a great job.

I rewrote this piece of code and my understanding is that scope() does not know any thing about variable x declared outside of it instead having permission issue.
Please note that I developed my understanding that any variable outside of function (unless that variable is passed as an argument or made global) has no idea about it.

and if i write my first statement to change x with in scope it would actually declare a new variable x having scope with in the scope funtcion.

This works fine
x="max"
print("first" + x)
def Scope():
x="haris"
print("sec" + x)
Scope()

but if i do like this it would error out not because of permission issue by rather scope of the variable.
x="max"
print("first" + x)
def Scope():
print(x)
x="haris"
print("sec" + x)
Scope()

Why is global considered bad programming practice?

[BurtMeister]

I don't get how x = whatever outside a function isn't a default global variable? I'm pretty sure in JS it is a global variable or a public variable.

[danz]

wait so is the first variable a global one or a local one
