Help me please!

Question

Why "is" evaluates to True in the first case and to False in the second?
First case:
a = 247
b = 247
print((a is b) == (a == b))
>>> True
Second case:
a =[2,3,4]
b =[2,3,4]
print(a is b)
>>> False
Also please let me know where can I found more on this "is".
Thanks in advance!

Answer 1

The "is" operator checks if 2 values refer to the same object, while == checks if their values are equal. When comparing object, it returns false even if they have the same values. It only returns true if you specifically assign it go
