Implement a function that validates whether given bracket-string (both single-type and multiple-type) is valid.
"""Implement function(s) to validate whether specified bracket string is valid.
For a string to be valid, it has to have the same amount of the brackets of the
same type (naive, simple implementation) and these bracket types cannot cross
(complex string/implementation) - just like they couldn't in a math. equation.
Solution to this exercise typically uses stack and pushes symbols onto it as
they are read, and pops them from its top as their counter parts are read.

Resume Browser Work from File

Why and What?

When I am working on something that I know I will get back to in a while and have to switch context (sometimes even a machine and an environment), I want to save all the relevant opened tabs from my browser to reopen them later. Ideally, I would like to avoid saving them to my bookmarks and rather save them together with a project (context) I was working on.

Before I wrote this small utility, I used to store the links in markdown format as a list with description of what I can find under given links. That was rather impractical and took a long time to initially write down, and also open later on.

With the utility, I can now save the links into the sources.txt file, one link per line. Then I just check-in the file together with the project into the VCS. When the time comes to start where I left of, I just run python path/to/directory/with/sources.txt/file and it opens all the tabs in my default browser.

def ips_in_net(ip='', subnet=''):
from ipaddress import ip_address, ip_network
hosts = list(ip_network(f"{ip}/{subnet}", strict=False).hosts())
return [f"{host}" for host in hosts]
