I have been trying to postpone the creation of an object inside a function. I am aware that if you want to modify a global variable you must use the global keyword. But, if I run that code:

testvar = 0

class myobject(object):
    
    asd = 'whatever'
    
def afunc():
    global testvar
    testvar = myobject()
    

After executing afunc(), testvar is equal to 0.
Why ???
