How to check out a branch with GitPython
提问by Alex Spurling
I have cloned a repository with GitPython, now I would like to checkout a branch and update the local repository's working tree with the contents of that branch. Ideally, I'd also be able to check if the branch exists before doing this. This is what I have so far:
我已经使用 GitPython 克隆了一个存储库，现在我想签出一个分支并使用该分支的内容更新本地存储库的工作树。理想情况下，我还可以在执行此操作之前检查分支是否存在。这是我到目前为止：
import git
repo_clone_url = "[email protected]:mygithubuser/myrepo.git"
local_repo = "mytestproject"
test_branch = "test-branch"
repo = git.Repo.clone_from(repo_clone_url, local_repo)
# Check out branch test_branch somehow
# write to file in working directory
repo.index.add(["test.txt"])
commit = repo.index.commit("Commit test")
I am not sure what to put in the place of the comments above. The documentationseems to give an example of how to detach the HEAD, but not how to checkout an named branch.
我不知道用什么来代替上面的评论。该文档似乎给出了如何分离 HEAD 的示例，但没有给出如何检出命名分支的示例。

If the branch exists:
如果分支存在：
repo.git.checkout('branchename')
If not:
如果不：
repo.git.checkout('-b', 'branchename')
Basically, with GitPython, if you know how to do it within command line, but not within the API, just use repo.git.action("your command without leading 'git' and 'action'"), example: git log --reverse=> repo.git.log('--reverse')
基本上，对于 GitPython，如果您知道如何在命令行中而不是在 API 中执行此操作，只需使用repo.git.action("your command without leading 'git' and 'action'"), 示例：git log --reverse=>repo.git.log('--reverse')
