I became unemployed again. I decided to study while looking for a job in order to improve my technical skills during the NEET period.
A long time ago, he was enthusiastic about the Perl language, but lived away for several years. Perhaps he seemed to have an affair, he had an attitude that he couldn't understand at first glance in the Perl language. It may be a problem for me who didn't give it up, but I'm going to divide it as it is. It's a huge book fee that I don't know how much I spent, but I think there was a problem with my one-sided tribute and decided to give up. I'm going to change my mind and get serious about different scripting languages. However, I haven't decided on my favorite yet.
I have two ideas now.
I want to do text processing, but apart from the Perl language, the above two points seem to be hard to compare. The Go language was easier to get used to when I touched it. After a few weeks or months, you may have forgotten how to use it, even if it's a small process. Still, the daily life of text processing does not change (and I don't use it every day, so I forget about it). Therefore, from the GUI screen, I decided that there would be no problem in text processing even if I forgot the processing contents.
So, if it's GUI programming, Python will be better off. GUI development in Go language is still under development, and it is a high threshold for me who has escaped from Perl language.
Therefore, first aim to learn the Python language. Above all, it seems to have a high affinity with Excel, and the range of applications seems to be wide-ranging.
Even if you can do the same thing in Go language, you can't work on it because there is no information. I'm very sorry, but it can't be helped.
With this post, I'm completely separated from the Perl language. Don't be afraid to become a Buddhahood.
I have Python3 installed, and I have pip3 and pygame installed. I run the program ...

Why? You have Pygame installed, right?
I don't like it and the environment construction has failed, but it seems that it will fail just by installing it normally.
Hereafter, reinstall it.

Why?
I don't know about clang, but XCode is already installed, and the console version is already installed. However, it may be because the version remains old. When upgrading the version, it is necessary to upgrade each OS. I want to avoid it. It's still too early to make the default shell Zsh.
By saying that, look for other measures.
I don't know what to do, so I decided to install the program described in the URL displayed in the error.

If you've read this far, you may have forgotten the first explanation, but you've got an error running the pygame sample. However, I was able to run the sample program of the book I was reading for study, and no error occurred. Therefore, I am satisfied with it.
As I mentioned at the beginning, GUI development of Go language is hopeless, but for the time being. With that said, as in "Introduction to Easy Go Language", enter commands, build a Go language development environment, and then introduce a GUI development environment.

Why? Certainly, in the book, it was as if something was written at the end of the path shiny, but there was no specific description. So I thought I could omit it ...

[chesscommands@Qiita ~] $
you're kidding. I wondered if I succeeded when I typed in the symbol I thought I would omit.
And I made a sample program according to the book, but it doesn't work well.
prompt
Failed to get state - detached from the process
Process exiting with code: 0
The program ends abnormally. Yup.
However, it looks like it was done, so let's judge that there is no problem. After all, it's far from full-scale GUI development, and I'm reading the first page of a beginner's book ... It's a long way to go, but I have time because I'm unemployed. Let's acquire technical skills and do our best in job hunting.
I like Python, which makes it easy to start GUI development (although it took a lot of time to build the environment). It's easy to motivate because it's GUI development. It's good to mess around on the console, but it's easy to lose sight of your purpose, so I want to make a small game with GUI development to gain confidence in order to clarify my motivation. Until then, if you are told that it is not suitable for programmers because you will not program unless you make an effort.
Go language is easy to learn (I like the automatic formatting of the IDE). And both are difficult to learn.
No way, I wouldn't spend a few weeks building an environment ... that's all.
PS. It's also unpleasant that "~ / .dotnet / tools" is included in the PATH. I think it's a useless and garbage path, but I can't erase it. Creepy.
