- Extracting a method
- Processing duplicates
When the Extract Method refactoring is invoked , PyCharm analyses the selected block of code and detects variables that are the input for the selected code fragment and the variables that are output for it.
The detected output variable is used as a return value for the extracted function.
Python Extract Method example

The selected code fragment will be replaced with a function call.
If duplicate code fragments are encountered, PyCharm suggests to replace them with the calls to the extracted method:
