zScan - a Super simple subdomain scanner

The other day I was catching up to Joe Helle's Python 3 tools series on YouTube and got inspired to give the subdomain scanner a try. I'm not a coder so the code could be ugly, any feedback is welcome!

zScan is a Subdomain enumeration tool made by Tzero86

optional arguments:
  -h, --help            show this help message and exit
  -sd DOMAIN, --domain DOMAIN
                        Single Domain to enumerate
  -dl DOMLIST, --domlist DOMLIST
                        Custom domain file to use
  -sl SUBLIST, --sublist SUBLIST
                        Custom subdomains file to use
  -o OUTPUT, --output OUTPUT
                        Output file

Features

• Scan for subdomains based on given domain
• Save results to a file
• Scan progress bar
• Terminate Scan by pressing CRTL+C
• Support to specify output file to save the results to

Currently working on

• Support for custom domain and subdomain files

Things to fix or add

• Add support to specify a file with subdomains
• Add support to specify a file with domains
• Add support to limit the number of subdomains to scan
• TO FIX: When pressing CRTL+C, the scan output on the terminal gets messed up.

I'm going to add a few more features to this, like being able to specify how many subdomains to try. I'll be adding more features as I get the time to do so.

Thanks!
