How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

apt-get update && apt-get install gdb

For pupil: all binary can be downloaded http://pan.baidu.com/s/1hqH2Pko

After overwriting, maybe need to run chmod +x /path/to/sublime_text. For linux default installation, need to add sudo.

For programmer:
