If we finished a program in Python, and we want to share it for our friends their computer have no Python (Maybe they won't to install it.), we can use "PyInstaller" to convert our program to be a exe file.

After I watching the movie "Joker", two days have passed. It's not a straightforward, wonderful fighting "Hero movie". It is different from Marvel move, but it has its own step. It's a DC darkness story.

Before we started, I want to say, I don't have professional movie review skill, I just want to share my thinking after I watching it.

PyInstaller is a very convenience Python module, its goal is make a exe file from Python file.

Because that, we can convenience to give our program to our friends if their computer have no Python (That's possible!)

PyInstaller is a module you need.

The modern life has disappeared from Gmail, sending mails to the professors has become the most important means of communication for graduate students.

In my graduate life, I have to switch between Linux and Windows, so I have been worried about the backup of my files. I have an FTP server, but I still need more way to backup.

I recently started to want to make a more beautiful interface. So I think I can't place the components casually as before.

Thanks to this, I want to record two very important processing methods today - "How to hide components, show components", "How to make components automatically fit to window size".
