While loop repeat

[Runner83]

Hi,

I am new to python and just playing around with basic tasks at the moment.
The project I am working on at the moment is a password validation script.
I have written this in two formats, on with just a while loop and the second
in a function with the same while loop.
When running the first method, the loop runs until the condition is met. While running the second
method, the loop runs through once and then stops. Is there a way to use the function and loop
until the condition is met or would it be with just sticking to the first method? Please see code below:

Method 1:

#///The following code works///
#import re
#password = input("Please enter a password: ")
#x = True
#while x:
# if len(password) < 8 or len(password) > 16:
# break
# elif not re.search("[a-z]",password):
# break
# elif not re.search("[A-Z]",password):
# break
# elif not re.search("[0-9]",password):
# break
# elif not re.search("[@£$]",password):
# break
# elif re.search("\s",password):
# break
# else:
# print("Valid password")
# x = False
# break
#if x:
# print("Not a valid password")

Method 2:

import re

def password_1(x):

while True:
#input("Please enter your password: ")
if re.search(r'[" ",_]', x):
print("Please enter a valid password")
elif re.match(r'[a-z,A-Z,0-9]',x) and re.search(r'[!@#$%^&*-+=]',x) and len(x) >= 8:
print("Password accepted")
break
else:
print("Please enter a valid password")

return x

password = input("Please enter your password: ")
password_1(password)

Thanks in advance

Could you please edit your message with python in brackets [].
It would be much easier to read because We can see where are the if or while loops.
With(without the "" and the spaces between python and the brackets):
"[ python ]"
"[ /python ]"

I didn't know the existence of the "re.search" function.
But here is something simple that works (I didn't write the whole alphabet):

ar=['a','b','c','d','e','f','g']
def password_1(x):
    i=0
    while password == ' ':
        print("Please enter a valid password")
    while i<len(password) and (password[i] in ar):
        i+=1
    if i>len(password)-1:
        print("valid")
    else:
        print("invalid")
password = input("Please enter your password: ")
password_1(password)

You're welcome.

@MasterJediKnight7 here is the code for the function which is method 2

import re

def password_1(x):
    
    while True:
        #input("Please enter your password: ")
        if re.search(r'[" ",_]', x):
            print("Please enter a valid password")
        elif re.match(r'[a-z,A-Z,0-9]',x) and re.search(r'[!@#$%^&*-+=]',x) and len(x) >= 8:
            print("Password accepted")
            break
        else:
            print("Please enter a valid password")

        return x

password = input("Please enter your password: ")    
password_1(password)

@JediMasterKnigh7 and here is the first method which has more lines of code but repeats the question for user input until the conditions are met:

#///The following code works///
import re
password = input("Please enter a password: ")
x = True
while x:
    if len(password) < 8 or len(password) > 16:
        break
    elif not re.search("[a-z]",password):
        break
    elif not re.search("[A-Z]",password):
        break
    elif not re.search("[0-9]",password):
        break
    elif not re.search("[@£$]",password):
        break
    elif re.search("\s",password):
        break
    else:
        print("Valid password")
        x = False
        break
if x:
    print("Not a valid password")

I'm sorry, I can't help you right now.
I'm kind of on a tight schedule.
