After recently changing .pylintrc (see [1]) we discovered that the presubmit check always checks all the python files when just one python file gets updated. This CL moves all these files one step closer to what the linter wants. Autogenerated with: # Added all the files under pylint control to ~/Desktop/to-reformat cat ~/Desktop/to-reformat | xargs sed -i '1i\\' git cl format --python --full This is part 1 out of 2. The second part will fix function names and will not be automated.
