using regex for password validation

[Sadaka Technology]

hello guys,

I have this pattern for password validation (regex):

I want these rules to be applied:

Minimum 8 characters.
The alphabets must be between [a-z]
At least one alphabet should be of Upper Case [A-Z]
At least 1 number or digit between [0-9].
At least 1 character from [ _ or @ or $ ].

and this pattern:

passwordpattern = "^(?=.[a-z])(?=.[A-Z])(?=.\d)(?=.[@$])[A-Za-z\d@$!%?&]{8,}.$"

my only issue is that I want to add the symbol () and symbol(.) in the pattern 
where only it accepts $ and @, I tried adding generally like [@_$] not working

Pyrebase auth

[Sadaka Technology]

I am using signup method:

user_signup = auth.create_user_with_email_and_password(email, password)

and my firebase rules are:

{
  "rules": {
".read": false,
".write": false,
  "$localId":  {
".write": "auth.uid === $localId",
".read": "auth.uid === $localId"
  }  
  }
}

I used:

data = {"item1":"hat","item2":"car"}
results = db.child("users").update(data, user['idToken'])

the only way to patch (update) is to use:
".read": true,
".write": true,

which means that anyone can read or write in my database where I only want the 
user to write or read if his idtoken or localid is authorized, even if data is 
outside his region for ex:

database:

"number_of_users":"2"

"userlocalid":
 {"item1":"hat"}
 {"item2":"car"}

kivy,,, assigning global variable

[Sadaka Technology]

class main(..):

def init.:
super.
button = Button(on_release=self.on_click)

def on_click(self,screen,*args)
  self.clear_widgets()
  if screen == '2nd':
  float = 2nd()
  elif screen == '1st':
  float = 1st()
  self.add_widget(float)

class 2nd(...):
string_text = StringProperty()
def init.:
super.
Text = TextInput(text=self.string_text)
 button=Button(on_release=self.on_click)

def on_click
  self.parent.on_click('1st')

class 1st(...):
 


#my only issue is in class 2nd() how can I change the value of the variable 
string_text, if I am clearing widgets and adding widget again in parent class ( 
main()), then string_text will again equal to empty ,   I tried to add 
string_text variable in main() but the same issue I am getting, how can I save 
the string_text in 2nd() if am removing it and adding it again ?
