Help with Global/Coerced Variable (Understanding Scope)

[Rev2k]

Hi, I'm going through the python in easy steps book and have hit a snag with global/coerced variables.
I've copied the code exactly from the book but not getting the return I expect.

Here is the code:

global_var = 1
def my_vars():
    print( "Global Variable:" , global_var )

    local_var = 2
    print( "Local Variable:" , local_var )

    global inner_var
    inner_var = 3

    my_vars()
    print( "Coerced Global:" , inner_var )

This is what I get back when I run it:

Error:
C:\Users\rev\PycharmProjects\untitled1\venv\Scripts\python.exe C:/MyScripts/scope.py

Process finished with exit code 0

What I should be getting back is:
Global Variable: 1
Local Variable: 2
Coerced Variable 3

Any ideas as I've copied this exactly from the book.
Thanks in advance

You need to call the function. Add this line to the end:

my_vars()

Thx for the reply ich - I'm now getting this back(not even the full return as it goes on forver and is too large to post):

Error:
Global Variable: 1
Local Variable: 2
Global Variable: 1
Local Variable: 2

Show your modified code. The line I asked you to add should not be indented.

modified code:

global_var = 1
def my_vars():
    print( "Global Variable:" , global_var )

    local_var = 2
    print( "Local Variable:" , local_var )

    global inner_var
    inner_var = 3

    my_vars()
    print( "Coerced Global:" , inner_var )
my_vars()

I think you shouldnt be calling my_vars() inside the definition, that is which causing the loop.

global_var = 1
def my_vars():
    print( "Global Variable:" , global_var )
 
    local_var = 2
    print( "Local Variable:" , local_var )
 
    global inner_var
    inner_var = 3
 
    #my_vars()  
    print( "Coerced Global:" , inner_var )
my_vars()

Output:
python test4.py

Global Variable: 1
Local Variable: 2
Coerced Global: 3

Best Reegards,
