looking at:
x = 'global'
def f():
def init():
global x in f
x = 'in f'
def g():
print x
init()
g()
I don't really know whether to call explicit or implicit the fact that x in g
is not the global one. And contrast with
x = 'global'
def f():
x = 0
def init():
global x
x = 'in f'
def g():
print x
init()
g()
or consider
x = 'global'
def f():
global x
def init():
global x in f
x = 'in f'
def g():
print x
init()
g()
