Error when length less than 4 in Provider().password()

[jianda1013]

I got AssertionError: Required length is shorter than required characters when using Faker().password(length = 2)

the error occurs when the input length is less than the character pool.

here is the current code
https://github.com/joke2k/faker/blob/master/faker/providers/misc/__init__.py#L144

        choices = ""
        required_tokens = []
        if special_chars:
            required_tokens.append(self.generator.random.choice("!@#$%^&*()_+"))
            choices += "!@#$%^&*()_+"
        if digits:
            required_tokens.append(self.generator.random.choice(string.digits))
            choices += string.digits
        if upper_case:
            required_tokens.append(self.generator.random.choice(string.ascii_uppercase))
            choices += string.ascii_uppercase
        if lower_case:
            required_tokens.append(self.generator.random.choice(string.ascii_lowercase))
            choices += string.ascii_lowercase
        assert len(required_tokens) <= length, "Required length is shorter than required characters"

maybe need to separate the required token and the available token for the input?

To resolve the error, you can automatically increase the password length if it is less than the number of required categories, setting it at least equal to the number of required categories. Subsequently, the characters are completed with random ones from the available pool, still respecting the categories, and finally they are mixed to avoid predictable patterns. For example:

# If the required tokens exceed the requested length, adjust the length to be at least the number of required categories
if len(required_tokens) > length:
    length = len(required_tokens)

# Create the password starting with the mandatory required tokens
chars = required_tokens

# Add random characters from the available pool until the password reaches the requested length
while len(chars) < length:
    chars.append(self.generator.random.choice(available_tokens))

# Shuffle the characters to avoid predictable patterns and ensure randomness
random.shuffle(chars)


# Return the password as a string, truncated to the desired length
return ''.join(chars[:length])
