* Update password_generator.py 1. Use secrets module instead of random for passwords as it gives a secure source of randomness 2. Add type annotations for functions 3. Replace ctbi (variable for the characters to be included) with a more meaningful and short name 4. Use integer division instead of obtaining the integer part of a division computing a floating point * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
