Problem with my code

[Godx]

I'd like to create 5 defs with this.
In the first round it should get the first value of every string.

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

so if 1 = 1:

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