像git <tab>这样的test.py自动完成功能

Question

当我发出git with tab时，它可以自动完成一个列表，我想写一个test.py，当我输入test.py和tab时，它可以自动完成在test.py中定义的给定列表，这可能吗？

$ git [tab]  
add                 branch              column              fetch               help                mv                  reflog              revert              stash               
am                  bundle              commit              filter-branch       imap-send           name-rev            relink              rm                  status              
annotate            checkout            config              format-patch        init                notes               remote              send-email          submodule           
apply               cherry              credential          fsck                instaweb            p4                  repack              shortlog            subtree             
archive             cherry-pick         describe            gc                  log                 pull                replace             show                tag                 
bisect              clean               diff                get-tar-commit-id   merge               push                request-pull        show-branch         whatchanged         
blame               clone               difftool            grep                mergetool           rebase              reset               stage

您要查找的方法是：readline.set_completer。此方法与bash shell的readline交互。它很容易实现。示例：https://pymotw.com/2/readline/
