Thanks!
Hi,
I have used goto instruction a lot when I started to program in Basic ( an Amstrad CPC 🥹). In this context goto had logic. But in modern languages like python I think it is a very bad idea:
- Understand the logic is more complex
- Functions and methods are a better and more powerfull alternative
- It is dangerous: add or remove a new line of code could have bad consequences
Regards
The most probably! Thanks a lot!
You are more lucky than me! 😂
You can use global variables, it is true, but I prefer singleton because I have all config variables and logic encapsulated in a class. The first time the singleton object is created it reads all the config variables from a file, and with its methods get and set manages them. The Config class doesn't know the parameters names of the config file neither the number, it dynamically reads the file and creates the attributes, so It is a very reusable code that when you program using OOP is a more natural way than implementing like a module.
Related to this, I group config variables by sections so it is more clearly for me, then the singleton object dynamically creates an array for each section, and a variable into the array for every variable in this section of the config file. Access to the config info is as easy like this:
conf = Config()
conf.get('DB', 'server')
conf.get('DB', 'login')
conf.get('DB', 'password')
I use a singleton class called Config (some times I use it as a Cache too)

5G was only at example of new technologies. It is true that wireless internet need to be deployed in Africa and other areas, but Starlink need to be deployed in the space too. And in a short/medium term future will be easier upgrade earth based antennas than satellites in orbit. In the middle of the sea are satelital communications for important info actually, and this must be enough. See a film online in the middle of the Atlantic is not as important as the knowledge that the Galaxy give us (my personal and subjective opinion)
There are more options to get internet access, the new ones like 5G are wireless and with a huge bandwidth. Is really internet access in the middle of the nothing a priority? More than the potential knowledge about who we are and from where we come? I don't believe in a World where people doesn't know enjoy the nature and the wild places without internet.
Hi! Other great book is "Fluent Python". I think PCC could be better as first contact and then this one as next step.

If your instance is lemmy.ml the most probably is due to a overload on the server
I fully agree with the post. Except for a fast prototyping or a short personal script where it could be not necessary, type hint is a must. The subject is not only to guarantee that the program now runs without errors, but it will be still working right in the future too, even after a developer (either the original or other) make changes to the code.
