1. Run pyformat scripts/hiddenapi -s 4 --force_quote_type none -i to fix formatting. 2. rename restricted variable names (e.g. variable name "input" has been changed to "csvfile") 3. use pylint: disable=<X> where fixes are not obvious Test: m merge_csv signature_patterns signature_patterns_test Test: pylint --rcfile tools/repohooks/tools/pylintrc <file1> <file1_test> Bug: 195738175 Change-Id: I800a208f9c0ee1d32e68e4b20fd5933b3ab92c0e
