Today, I would like to share with you the relevant knowledge points about how to use the python password generator. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

Usage

1. Randomly generate N-bit passwords. To put it another way, this is actually the equivalent of preparing a set of uppercase letters, a set of lowercase letters, a set of numbers, a set of special characters, randomly picking N characters from them, and then arranging them in a row. You see, so we can't turn general requirements into practical problems that can be solved programmatically?

2. The password should contain at least one uppercase letter, one lowercase letter, one number, one special character, and can specify the password length-to meet this requirement, there is an easy way to start from scratch and put the password first.

The uppercase letter, the second lowercase letter, the third number, the fourth special character, and the remaining NMUI 4 characters are put in any character in turn.

3. To solve the problem of randomly fetching words from the character set-- we have learned the random.randint () function before, which can randomly generate a number. We use this random number as an index to take the value of the character set (the character set can be in the form of str or list), so as to achieve the purpose of randomly fetching characters.

4. Receiving the password length through the command line interaction is relatively simple, using input ().

Example

Import randomchar def generate_password (length): if length < 4: raise ValueError ('password is at least 4 digits') random_char = randomchar.RandomChar () password = random_char.uppercase () password + = random_char.lowercase () password + = random_char.digit () password + = random_char.special () count = 5 while count 20: raise ValueError ('password length does not match') password = generate_password (password _ length) print (password) above is all the content of the article "how to use python password generators" Thank you for reading!
