So, this does not make sense to me in terms of the following snippet
from the official python docs page:
https://docs.python.org/3/faq/programming.html
"In Python, variables that are only referenced inside a function are
implicitly global. If a variable is assigned a value anywhere within
the function’s body, it’s assumed to be a local unless explicitly
declared as global."
So, I would then assume that if I explicitly include a variable name
inside the global statement, then even just assigning it a new value
should update the variable in the global context, outside the
function?
Yes. Note that the "global" namespace is the module in which the
function is defined.
x = 1
def f(n):
global x
x += n
This updates the `x` global variable in the module where `f` was
defined.
If you import `f` and use it in another module it will _still_ update
`x` in the original module namespace.
