Tell us what’s happening:

Hello all, i am not sure where I am going wrong with this step, please help. The code says I should complete the fourth pattern non alphanumeric character

Your code so far

import re
import secrets
import string


def generate_password(length, nums, special_chars, uppercase, lowercase):
    # Define the possible characters for the password
    letters = string.ascii_letters
    digits = string.digits
    symbols = string.punctuation

    # Combine all characters
    all_characters = letters + digits + symbols

    while True:
        password = ''
        # Generate password
        for _ in range(length):
            password += secrets.choice(all_characters)

# User Editable Region

          
        constraints = [r'\da-zA-Z']   

# User Editable Region

    return password
    
# new_password = generate_password(8)
# print(new_password)

pattern = r'\.'
quote = 'Not all those who wander are lost.'
# print(re.findall(pattern, quote))

This is the starting code:

constraints = [
            (nums, r'\d'),
            (lowercase, r'[a-z]'),
            (uppercase, r'[A-Z]'),
            (special_chars, r'')
        ]

The fourth pattern is the string right after special_chars. You need to add content to it, without deleting anything else.

This is what I have so far, but I am still not sure what I should be doing to satisfy

'Sorry, your code does not pass. Hang in there.

  1. You should complete your fourth pattern to match any non-alphanumeric character.’

import re
import secrets
import string

def generate_password(length, nums, special_chars, uppercase, lowercase):
# Define the possible characters for the password
letters = string.ascii_letters
digits = string.digits
symbols = string.punctuation

# Combine all characters
all_characters = letters + digits + symbols

while True:
    password = ''
    # Generate password
    for _ in range(length):
        password += secrets.choice(all_characters)
      
    constraints = [r'\da-zA-Z' ']   
return password

new_password = generate_password(8)

print(new_password)

pattern = r’.’
quote = ‘Not all those who wander are lost.’

print(re.findall(pattern, quote))

4

You deleted the other items in constraints. Reset the code for this step and try again without deleting anything.

Your pattern should use a character class, which is indicated by square brackets. Within the square brackets, you want to start with a ^ to negate the pattern, and then combine a-z, A-Z, and 0-9.

oh gosh thanks just forgot how to read properly there for second.
