Anytime you want to check if an object is iterable, you just call the function as follows: # Test 1score=90ifisiterable(score):print("Object is iterable")else:print("Object is not iterable")# ✅# Test 2my_list=[1,2,3]ifisiterable(my_list):print("Object is iterable")# ✅else...
This is why the most reliable way to check if an object is iterable is to pass the object to theiter()built-in function. Theiter()function raises aTypeErrorif the passed-in value doesn't support the__iter__()method or the sequence protocol (the__getitem__()method). ...
