this question has answer here:

i trying set dictionary staff's salary in python. want create 2 functions, getname() , getsalary() tried: 

empdic={}  def setname(n):  empdic={'n':''}

and in python interactive 2.7 typed:

>>>setname('marson')  >>>print empdic  {}

the result still empty dictionary, how can deal that?

you need modify original dict:

empdic={}  def setname(d, n):    d[n] = ""  setname(empdic,"marson")  print(empdic) {'marson': ''}

you creating new local variable empdic in function, using string "n" not name n passed in function.
