Python database problem

Question

import dbm
with dbm.open('contas','c') as contas:
contas['0'] = '0'
contas['1'] = 'a'
contas['2'] = 'b'
contas['3'] = 'c'
contas['4'] = 'd'

def Validation():
user = ent.get()
passw = ent2.get()
val1 = False
val2 = False
with dbm.open('contas','c') as contas:
for i in contas:
print(val1,val2)
if user.encode() in contas:
val1 = True
if passw.encode() in contas[i]:
if passw.encode() == '':
val2 = False
val2 = True
print(passw,contas[i])
print(user, passw)
if val1 == True and val2 == True:
stats['text'] = 'Valid'
else:
stats['text'] = 'Invalid'
#When i clikc the Validation Button my program prints:
False False
b'a'
False True
b'b'
False True
b'c'
False True
b'd'
False True
b''

#When i click the button with empty password entry, the program always print the #validatoin password as True, but if i use a strange password(which is not contained in #contas[i]), my pass validation works and print False. Why empty box is valid?

print(contas.keys())
[b'1', b'2', b'3', b'4', b'0']

Answer 1

maybe try

"if Len(passw.encode) == 0:
val2 = False"
