def define_closure(member):
def Kagemusha():
return "%s is my decoy" % member
return Kagemusha
aKgms = define_closure("7of9")

print(whoIsKagemusha)
whoIsKagemusha = bKgms()
print(whoIsKagemusha)
whoIsKagemusha = cKgms()
print(whoIsKagemusha)
Ergebnis
Success time: 0 memory: 23304 signal:0
7of9 is my decoy
