Problem with my code

[Godx]

Hello Guys,
i am working on a school project and could need some help.

command = [getuser(),getpw(),getnewuser(),getnewpw(),getreppw()]
variable = [user,pw,newU,newpw,reppw]
surce = [e1,e2,f1,f2,f3]


for i in range(5) :
    def command[i]:
        global variable[i]
        variable[i] = surce[i].get()
        return variable[i]

As you see i have to create lots of defs and like to shorten this,
because i have to add even more variables and it would be way more efficent if i
could just add it to the list, instead of creating a new def.

def getuser():
    global user
    user = e1.get()
    return user

def getpw():
    global pw
    pw = e2.get()
    return pw

def getnewuser():
    global newU
    newU = f1.get()
    return newU

def getnewpw():
    global newpw
    newpw = f2.get()
    return newpw

def getreppw():
    global reppw
    reppw = f3.get()
    return reppw

Thanks for your help.
