Invert boolean

Last modified: 21 July 2022

This refactoring aims to flip the value of a Boolean variable and all its usages from True to False and vice versa.

Example

Before

After

def foo():
    abc = True
    return abc
def foo():
    abc = False
    return not abc

To invert a Boolean variable, follow these steps

  1. Place the caret at the name of a Boolean variable.

  2. From the main menu, choose Refactor | Invert Boolean.

  3. In the dialog that opens, click Preview to view the suggested changes in the Find tool window, or Refactor to invert the detected occurrences silently.
