To verify manually all your recent changes compared to the master branch by name you can run

git diff --name-only master
package/file1.py
other/file3.py

Because of this we can run any script to it to verify our syntax is proper

git diff --name-only master | xargs flake8
package/file1.py:2:1: F401 'logging' imported but unused
other/file3.py:358:9: F821 undefined name 'logger'
