How to use:

1. Save as passgen.py
2. Make it executable (optional): chmod +x passgen.py
3. Run:

python3 passgen.py                    # 16 character password
python3 passgen.py -l 24              # 24 character password
python3 passgen.py -c 5               # Generate 5 passwords
python3 passgen.py --no-special       # No special characters
python3 passgen.py -l 20 -c 3         # 3 passwords, 20 chars each
