Inspectopedia 2025.2 Help

__init__ method that returns a value

Reports occurrences of return statements with a return value inside __init__ methods of classes.

Example:

class Sum: def __init__(self, a, b): self.a = a self.b = b self.sum = a + b return self.sum

A constructor should not return any value. The __init__ method should only initialize the values of instance members for news objects.

As a quick-fix, the IDE offers to remove the return statement.
