Git in Pycharm

Starting a version controlled project

In Pycharm, you have to enable a version control integration. There are many choices, but we will use Git. As you can see, Git appears in the toolbar and a git window appear bottom of the window. And you can identify the current branch that you are in. So the default branch name is master.

Let's try to write some code And add all contents that we write in a git repository.

In the commit window, we can see file project. But we had three important things. We have a textBox and two buttons. In the textBox, you can write a comment when you commit. The Commit button is used to save all change in your project. The Commit and Push is used to commit and push the project in a Git.

When you press the Commit and Push, a new window appears. You can see which branch and which commit that you push.
