Where to look for parameter that was just returned by signal?

QTabWidget has signal currentChanged(). And it returns index of current tab.
But how can I get this parameter in such expression: 

tabs.currentChanged.connect(lambda: foo());

def foo(index):
    ...

Where should I look for this parameter that was just returned?

Signals don't "return" anything. They can have parameters though, which is the case for currentIndex. If you want that argument passed to your function, you should try:

tabs.currentChanged.connect(lambda index: foo(index));
