Answer 1

pipreqs

pip freeze list all packages installed, use pipreqs. Pipreqs generate requirements.txt file for any project based on imports.

pip install pipreqs


Usage:
    pipreqs [options] <path>

Options:
    --use-local           Use ONLY local package info instead of querying PyPI
    --pypi-server <url>   Use custom PyPi server
    --proxy <url>         Use Proxy, parameter will be passed to requests library. You can also just set the

                          $ export HTTPS_PROXY="https://10.10.1.10:1080"
    --debug               Print debug information
    --ignore <dirs>...    Ignore extra directories
