The significance of this kind-examining lies during the operator's commonest use—in conditional assignment statements. In this use it appears being an expression on the appropriate facet of an assignment assertion, as follows:
A significant limitation of CPython is using a worldwide interpreter lock (GIL) on Each individual CPython interpreter method, which correctly disables concurrent Python threads in just one particular approach. Concurrency can only be realized with different CPython interpreter processes managed by a multitasking operating program. This complicates conversation concerning concurrent Python procedures, though the multiprocessing module mitigates this relatively.
Remember also that some forms let initialization, but don't enable assignment, or perhaps which the assignment operator as well as the constructor do fully different things. This very last is accurate for reference sorts, as an example:
