Python: determine if all items of a list are the same item [duplicate]

Answer 1

Best way to do this is to use Python sets.You need to define all_same like this:

def all_same(items):
    return len(set(items)) < 2

Test:

>>> def all_same(items):
...     return len(set(items)) < 2
... 
>>> 
>>> property_list = ["one", "one", "one"]
>>> all_same(property_list)
True
>>> property_list = ["one", "one", "two"]
>>> all_same(property_list)
False
>>> property_list = []
>>> all_same(property_list)
True
