Pylint is currently running python3.0 syntax and we are updating the pylint to python3.9. As a result we received a few warnings that have not been previously identified with python3.0 syntax. This code change will address those warnings raised by latest pylint check. The following alarms are addressed: 1. W0237 - Parameter '.' has been renamed to '.' in overridden method 2. E1101 - Instance of '.' has no '.' member (no-member) 3. W0127 - Assigning the same variable to itself 4. E4702 - Iterated dict is being modified inside for loop body 5. W0602 - Using global for '.' but no assignment is done 6. E1123 - Unexpected keyword argument '.'. in method call 7. W0238 - Unused private memeber '.' 8. E1121 - Too many positional arguments for methods call The following alarms are still remain suppressed: 1. W1514 - Using open with specifying encoding (python2 does not support this change) 2. W0707 - Consider explicitly re-raising using raise '.' from '.' (same as above) Test Plan : 1. Perform DC Regression Test and compare before and after code change 2. Ensure Tox can pass on both Debain and CentOS build server 3. Ensure pylint3 and pylint3.9 can pass without warning 4. Ensure ISO can be properly booted on both Debian and CentOS Story: 2008943 Task: 45832 Signed-off-by: BoYuan Chang <boyuan.chang@windriver.com> Change-Id: I6f3a25fd788a3bdc021067c624123132a716e5c8
