Sorry for this very basic question, but I don't understand why I should
add the global into the function body before using it.
This function works even if I don't add the global.
Just to try this out, I wrote this variant:
gname = 'Luis'
def doIt2(name=None):
if name is None:
name = gname
return name
print doIt2() --> returns Luis.
So, what's the point of writing the function this way instead?
def doIt2(name=None):
global gname
if name is None:
name = gname
return name
luis
