为什么我不能将 True 存储在 Set 中？

Question

I have this code:

mySet = {1,"2",3.0,True}
print("Set: " , mySet)

The output is

Set:  {1, 3.0, '2'}

What happened to the 'True'?

Answer 1

Because set save unique value one time and 1 and True == 1 are same. For this reason, you see 1 one time.

>>> {1,True}
{1}

>>> {0,False}
{0}

>>> {'1',True}
{'1',True}
