In this page I'm sharing whatever I believe can be useful to others. It will get messy in here!
Many times, I started learning python and I did learn the basics, but every time I encountered it, I was still lost. I did two of the courses of Dr. Charles Severance from Coursera and I did try to fill in the gaps. After watching many comparison videos about methods and what to do, I chose to get started with Python Crash Course - Eric Matthes. This book almost covers everything, and it has many examples. Also, most importantly, it is written in a very friendly language.
Shake and keep gas cartridge horizontal
If you have bought any kind of heater that works with liquid gas cans and the weather is cold, rotate the can and shake it a bit before connecting the heater, or else, the gas would not evaporate, and the device wouldn't work. I spent a whole night freezing in the tent thinking that the heater was broken, however, I just didn't know that I had to shake the gas cartridge.
Rerouting domain to the www domain
A huge problem that I had when I bought the domain to this website was that the default domain included the www. That means that in order to reach the website you should have typed www.parsakabir.com. So, after searching, i found out that I should reroute parsakabir.com to www.parsakabir.com. In Cloudflare DNS records panel, make a dummy DNS record with the following data: Type A, name @ and IPv4 address 192.0.2.1 and keep the proxy status on. Then go to the Rules tab and create a rule in the Wildcard pattern. The request URL should be https://parsakabir.com/* ( your website domain without www and the /* in the end) and the target URL should be https://www.parsakabir.com/${1} ( your website domain with www and /${1} in the end). This worked perfectly fine for me.
