Because Python isn’t strongly typed, sometimes PyDev doesn’t know what type a variable is – and therefore it cannot give you accurate code completions. Here’s how to make that better.
In simpler situations, PyDev works very well. For example:
emp = Employee()
Typing ’emp.’ will get you a good autocomplete.
Now, let’s say you have something like this:
emp = something.find_employee("dave")
Then ’emp.’ won’t get you anything – PyDev doesn’t necessarily know what type is being returned.
If you use python’s assert method:
emp = something.find_employee("dave") assert isinstance(emp, Employee)
PyDev now knows what type the variable is, and you’ll get more effective code completions.
When running in production, you can pass the “-O” flag to the interpreter, and it will ignore the assert statements.
