propper formating

[paracelsusx]

Hello, I am learning python3 using the python crash course book and I have decided to try to learn the most accepted way to properly format my code early on.
To do this I installed pycode with PIP.

Is it ok to be using 90 characters instead of 80? I find it a lot easier to work in 90 although I understand 80 is the standard, although there seems to be some debate over it when I search it online. I was thinking 90 is a small increase and may be accepted more among other programmers.

I'm doing the guest list tutorial in the crash course book, if your curious this is how my code looks. I hope it is somewhat proper and clean looking for my early stages. It is working at least.

There are guidelines, and there are rules. Rules should not be broken and there are generally good reasons for rules. Guidelines are "best practice". 80 chars is a guideline, has historic basis (ok, yes, I did program using punch cards that had 80 columns) and enhances readability. Would not sweat it.

I have decided to try to learn the most accepted way to properly format my code early on.

Good start would be to read and follow PEP 8 -- Style Guide for Python Code. It states quite categorically:

Limit all lines to a maximum of 79 characters.

For flowing long blocks of text with fewer structural restrictions (docstrings or comments), the line length should be limited to 72 characters.

However, one should consider it in context with A Foolish Consistency is the Hobgoblin of Little Minds

Regarding formatting your code - I saved it into file and my text editor complained about every blank line ('blank line contain whitespace').

There are formatted string literals (f-strings) for app 5 years now and they are much more 'human readable'. Also, if you enter manually list of names, why not enter them correctly instead of using .title over and over again? Also you should use datastructures like lists or sets which will significantly reduce lines of code and will make code much more readable.
